Would you want to meet a being from another planet? Its not going to be like ET. I tend to agree with Hawking. We cannot assume aliens would be benign. They would come here to take what they need and move on...like ID4, but without a wisecracking pilot and an eco-nerd who is also a hacker saving the planet.
the idea of man walking on the moon was thought to be absurd as recently as the 50's though. Accepted potential reality changes along with science.
I personally believe that extraterrestrial races must exist, mathematics dictates as such.
If they do, in the numbers and varying levels of advancement that the very same math predicts, than the idea that they have been to Earth is a reasonable likelihood.
Therefore I personally believe that beings from other planets have indeed been here. We've already been to Mars, and we are much younger than many of these ETs must be.
