Life on Earth Caused by Comet Impacts?
 
The impact of comets crashing into Earth's surface may have provided the energy to create simple molecules that formed the precursors to life, a new study suggests.

That conclusion, published in the June 20 issue of the Journal of Physical Chemistry A, was based on a computer model of such an impact's effect on a comet crystal initially made up of water, carbon dioxide and other simple molecules.

"Comets carry very simple molecules in them," said study co-author Nir Goldman, a physical chemist at Lawrence Livermore Laboratory in California. "When a comet hits a planetary surface, for example, that impact can drive the synthesis of more complicated things that are prebiotic they're life-building."

This is a more likely scenario:

Since you stumble over the most basic concepts in science, you're in no position to make any knowledgable claim about any scientific issue.

My hypothesis is that the building blocks of life were created during the Big Bang. Comets became the seeds of life, carrying the necessary amino acids and other molecules through space in the same manner as maple seeds floating on the wind. Some crash into gas planets, molten planets, or stony, dead planets and are lost. Some hit oceanic planets at just the right angle and voila! Life! Think of the comets as sperm and the oceanic planet (water) as the egg. Nature finds a useful model and utilizes it over and over. This would mean, of course, that there are billions and billions of inhabited planets.

Rho has it all figured out no reason to watch Morgan Freemans through the worm hole or go to church anymore.

Let me guess you're going to ask him what a comet is or when America was at its zenith.

Interesting article. Always cool to ponder the origins of life on Earth. We will probably never know, but I am for damn sure it wasn't what Genesis said.

It's turtles all the way down.
