Have Aliens visited Earth

[underrated29]

I dont know.....But one really interesting thing that always comes to mind when we talk about this stuff is:


In a painting by leonardo davinci he has a scene of a small city with people shopping, and boats sailing in the water and small houses and apple stands and fish stuff...But what really is interesting is that in the painting there is a small silver saucer in the sky. And there are a few people in the painting looking up at it and pointing to it.


This was painted by davinci who as we know was long before our time and the whole aliens thing.




Question is why does he paint that silver ufo and why are people looking and pointing at it if we have never been visited by aliens?



PS- when most people see lights at night and ufo type objects it is remote control helicopters. We used to attach the glow sticks, or lights to our RC compters and fly them at night in unison or on our own effing with people making them think they were UFOs or stuff. We would hover, take off fast, back up, whatever we wanted...Sooooo funny.

That was the first time i got crabs.



ps- heard about the kidneys- Sucks man. Havent made it big yet, I still need a couple more years. When I do, i got your back.

How did you hear about them?

And I'll be all right. I am overblown by the support here at campus. They are doing a spaghetti feed and fundraiser here to help cover my medical costs. Just touches me to pieces.

Bad timing, sure, but guess what. What a send off from University. Graduate in 10 days. It's gonna rock.

[underrated29]

Sickness. I hated school and I did not put in anywhere close to the amount of effort you did.

grats on the graduation....

Sneakers- he made a post called "oh noz". Weird guy he is, nice guy, but weird. Now dont go all Jay cutler on me now, start drinking away and such.

[Kaylore]

I hate the no options. I chose religious purely because I don't believe its mathematicaly impossible. I think when/if they come, it will be when both parties are ready. I certainly think when they come, they will do more than smash our wheat, steal cow testicals and raping Mock.

[Old Dude]

I doubt it because I can't see why they'd waste their time.

Any alien civilizations advanced enough to travel through trillions of miles of interstellar space would probably not see Earth as anything more interesting than an ant hill.

How many of you guys would spend all the time and effort to travel deep into the Amazon jungle, just so you could stand in front of some ant hill there and flex your stuff? Or read them Proust? Or solve their energy problems?

Judging by what I liked to do to anthills when I was a kid, I hope they're more evolved, or they might just decided to drop an asteroid on us to see what would happen.

Maybe they came for Halle Berry

I would.

[broncocalijohn]

Ask any human 150 years ago if we would be flying, going to the moon, etc. 150 years is nothing in this universe. Give an alien civilazation 10,000 year head start (or maybe even 100,000 year head start) and you could only wonder what can be done. I havent seen it personally but if life is formed on Earth, why couldnt it be somewhere else? Add the technology that they can have and it is very possible for them to be interested in Earth. Their experiment project.

[Phantom]

Why does an alien space craft, capable of traveling across the universe, need flashing colored lights on the outside. Do they use their blinker when they take a left at the Milkyway?

Dude, this so funny....

How do you come up with such original never heard before jokes?

You really do have a great talent for coming up with original jokes... keep it up!

[Rock Chalk]

No, but not for either reason given.

It is mathematically possible for a sufficiently advanced lifeform to travel both the galaxy and the universe in general.

The reason? Really really small needle in a ridiculously large haystack.

Earth is situated in a sparsely populated region of the galaxy where stars are further apart than the galactic norm. Since our technological footprint does not extend beyond this sparsely populated region of the galaxy (i.e., our earliest radio waves are still a stones throw away), it is bloody unlikely advanced aliens have been here.

The galaxy itself is huge. Assuming that there is another intelligent life form in OUR galaxy, statistically speaking that life form will likely be some 50,000 light years from us. Between us and them there are some 30 BILLION stars to explore and regions of the galaxy MUCH more interesting to explore than this particular region we occupy.

If aliens are out exploring, and not looking for resources, they would have had to exist longer than this galaxy has been around to find us. If aliens are looking for resources, they aren't going to be coming here ever.


If there is not an intelligent life form in our galaxy but in a nearby galaxy, then it is unlikely that we will ever meet them as the voids between galaxies are 10-100 times as big as the galaxy itself. (Andromeda, our closest galaxy, is 10 times further from the Milky Way as the Milky Way is across).

Mathematically it is entirely possible for ships to travel great distances even at sub-light speeds. Any civilization advanced enough to make these trips has solved their own aging problems (meaning their Biological technology is retardedly advanced), have a 100% efficient recylcing method so that food and water can be replaced without stopping, and have likely discovered a method of creating and storing anti-matter in an efficient manner on the go.

A single gram of anti-matter could take a ship the size of the space shuttle to the nearest star within a few decades. Creating a single gram of anti-matter on Earth would bankrupt the entire world (although, a single Obama is doing that too). Moreover, we humans have no practical way of storing anti-matter without you know, it mutually annihilating the compartment it is stored in.

Given that we are talking about aliens galavanting around the galaxy and/or universe, then these technologies (which are all possible) have been perfected by them.

[Rohirrim]

Plus, if the Big Bang concept is correct, then picture it as a giant stone thrown into a lake. The ripples would represent stars and galaxies and nebulae forming along rings moving out from the center - the original blast. Each ring would represent time emanating away from the original explosion. So, if there is life in the universe other than ours, the life that resides on galaxies and systems on our same concentric ring (logically) would be about at the same point of evolution as we are. The rings closer to the center would by much younger, while those out at the edge of the universe, where all the quasars reside, would be much older. So, the most advanced civilizations would be out on the edges of the universe, way too far to conceivably visit us by any technology we can imagine. And the life forms that are nearest to us within the universe, would also likely be nearest to us in development as well.

A massive worldwide conspiracy to cover up evidence is not a reasonable explanation.

If it were reasonable, then I could propose anything - for example, the flying spaghetti monster. Why don't you know about him? Because of a massive worldwide conspiracy.

Evidence for:
Millions of reported sightings from all around the world, claims of abductions, cattle mutilations, Roswell, numerous military officials claims they exist, unexplained videos, photos, recorded broadcasts, secret military bases and cover up initiatives, and people on there deathbed who swear they landed but had to take an oath of secrecy.

Anecdotal evidence is not based on facts nor careful study. It's pseudoscience and to believe it is faulty logic. A high ranking official saying they exist is an appeal to authority, yet another logical fallacy. A video or photo that is "unexplained" is just that - no explanation stands up to scrutiny. Although it's human to attempt to explain everything that we don't understand (look at ancient myths about lightning), it's not an invitation for you to insert your wildest fantasies, be it ghosts, gods, or aliens, into that which is unexplained.

I recommend you read "Demon Haunted World" by Carl Sagan, a man who has done more to contact extraterrestrial life than any other, to get a more scientific perspective on UFOs (unidentified flying objects).

[NYBronco]

I said yes to their earth visit not so much how often.

If you haven't watched Known Universe I would recommend it. The show just reinforces my beliefs.

Thank you, I'll be here all week....tip your waitress and try the veal!

[BroncoInferno]

I think that, given that mind-bogglingly vastness of the universe, that there our probably other life forms out there. But the nearest planet that could possibly contain life is at least several million light years away. The physics necessary to make the trip to Earth possible make alien visitation highly unlikely.

I pretty much agree with this post, except the mathmatics part. Yes, there are mathmatical equations that make such travels possible, but still highly unlikely.

One thing that some people mistakenly assume (not necessarily Alec in this post, but in general), is that evolution puts progress on an ever upward scale. That isn't the case. Most people assume that the longer a species exists, the more advanced it will become. Therefore, if a species has existed, say, two million years longer than humans, they would be more advanced than us. Of course, this isn't true. Just on Earth, there are many species that have existed far longer than humans, and yet we are the only species to have made the advancements we have. The advancements our species have made have been largely the result of blind luck, discoveries made by single individuals who often times weren't even looking to make the discoveries they made. Most of the technological advances have occured in the last two hundred years, after many millenia of ebb and flow between so called advancements and ignorance (compare the Dark Ages, for instance, with the Roman Empire). So, it may be that we Earthings are unique in our scientific/technological advancements/knowledge in the universe. It was a highly improbably occurance to begin with. In any case, I think that the probability that a species exists that could travel the vastness of the universe to find Earth (or, as Alec suggested, that even if they possessed those advancements that they would even find Earth) is highly unlikely.

huh?

As we currently understand things, only Tebow will be able to travel from one planet to another and on to another galaxy.

[ScottXray]

If a society was advanced enough to go star hopping through some advanced transportation system and they were curious about their surroundings (like us) AND they were carbon based, oxygen breathing
(like us) they very well might go looking for Planets that were oxygen based
atmosphere, same size as their home planet (within a certain +- factor for gravity) and capable of sustaining their life form.

Already we are starting to look for Earth like planets in the nearer stars that might be capable of being visited and or colonised (should we ever develope the means to get there). A part of it is our curiosity and a part of it is the fact that we know we are capable of being wiped out. But we are looking, even though we can't go yet, and they have alreasy spotted several candidates. They are probably wrong about them, but they have found several earth sized planets. So far most are not in the band where life as we know it is probably possible ( too far from their suns or too close)

But if that species had the tech to get somewhere, they probably would also have the tech to weed out the unlikely candidates. This would include stars with the wrong light spectrum (red giants, binaries, blue (too young), and a zillion other types of systems. When you start applying this weed out process and start selecting down, the number of systems that might work become a lot lower. (There is even speculation that a single Large Moon might be needed to promote life forming). Anyway, it might be that there are only a few million such planets in the entire galaxy, so a very advanced
tech society might decide to check them, or at least the closer ones. Assuming their transport system is FTL (sort of a warp drive so they don't spend years getting there and back) then it becomes possible , maybe even likely, that they may have visited earth at some time in the past (or might in the future.) It is still unlikely that they will be doing so RIGHT NOW, unless they are very far away, or are so advanced that they don't care.

At any rate, the point is that you don't check EVERY star, just the ones with earth sized planets , a certain distance from a G type (yellow) non variable sun that is of the right size and class. Those are the ones we would be checking if we had the means to go.

But the universe (even the galaxy) is so vast, that even such a weeding out process would likely be scatter shot, at best. But, as I said in my eariler post, it may be likely that there are life forms on other planets, but the likelihood of a significantly advanced (as we descirbe it) civilisation existing out there would require much slimmer odds than merely the existence of life.

Not the same as a UFO sighting which have claims from around the world throughout the history of man. From cave drawings, to biblical paintings, to videos, to photos. Not just one photo like Lochness monster but many many photos.

I do believe that most UFO videos and photos are more likely government test type vehicles than actual visits.

I didn't really see you convey anything that can convince me that military people lying on there deathbed would feel the urge to lie about Roswell. Or, for that matter, the many other scientists and government officials who come out and say they worked on projects that involved UFO type technology. Yes, I believe some of them are probably doing it for fame or money but I just can't believe that humanity is so corruptible that a 80 to 90 year old man would tell a whopper of a lie just before dying. Not to mention people from that era of time have different standards and codes that they lived by.

I recommend you read "Demon Haunted World" by Carl Sagan, a man who has done more to contact extraterrestrial life than any other, to get a more scientific perspective on UFOs (unidentified flying objects).

I will try to pick this up.
