- Relax, we’re far more complicated than that
- So Mars came?
Now that’s some distance!
- Seth has limited view. Tons of proof alien craft have been here - even from friggin' Us Air Force & he's still stuck in the 70's waiting for sum blips and bleeps on his Arecibo telescopes in PuertoRico. just saying. xxx 👽 xxx
- i suppose this leaves god dead ie if he ever existed in the first place
- Even if this is how life on earth began, that doesn't explain the origin of life in the universe. If life did originate off planet, then it is logical that life started somewhere in the universe and then spread to other locations. If so then it is just as likely that life on earth may be spreading to other locations but has not happened yet. What this means is that even though the universe is big, as likely as not, life has originated on earth and the rest of the universe is still lifeless
- This is exactly how I think life began on Earth. Did I just leave first comment?
