Asteroid Crashes Likely Gave Earth Its Water

Posted by samzenpus on from the space-water dept.

Diggester writes "Asteroids from the inner solar system are the most likely source of the majority of Earth's water, a new study suggests. The results contradict prevailing theories, which hold that most of our planet's water originated in the outer solar system and was delivered by comets or asteroids that coalesced beyond Jupiter's orbit, then migrated inward."

    If I was the creator of the universe, and had billions of trillions of planets capable of supporting life, what would be the most efficient 'delivery system' for me to use to deliver the "Seeds of Life" to them all? Frozen water. Lots of iceballs with the 'seeds of life' in them. Since all life on earth is based on water, and water is not native to earth, all of our water came from 'out there'. So, if life sprouted on this planet, it stands to reason it's happened everywhere. Ergo, we most likely are not 'alone'.

      If you can create universes, you don't need "delivery systems". You just speak your will into being.
