If abiogenesis is possible -- and right now it's not
even at the level of a hypothesis, as it's a religious
belief that can't be falsified -- and I do mean IF
abiogensis is possible, it couldn't happen here.
IF abiogenesis is possible, it happened elsewhere long,
Long, LONG before the earth even formed. It happened
on Mars long before the earth even cooled to the point
where it could sustain life! The universe is just so
vast, so old that if abiogenesis is possible it occurred
a ridiculous number of times before there was any hope
of a chance for it to happen here. So, if abiogenesis
is possible...
Life formed elsewhere, spread across space -- effectively
"Contaminating" other worlds -- and eventually fell here
on earth.
Mars began COOLING to the point where it couldn't sustain
the conditions we associate with life right about the
same time that life first appeared here on earth. Which
means Mars likely had a hundreds of millions of years
head start on the earth, for acquiring life...
If abiogenesis is real, if it can happen, there is a far
better chance that it leapt here from Mars -- a volcanic
eruption or "asteroid" impact through debris into space,
debris contaminated with life, only to fall on the earth.
But if abiogenesis is possible....
As of the present, best evidence says that life here on
earth has survived dormant, in rock, for as long as a
quarter of a billion years. This is no just long enough
to reach the earth from Mars or Proxima Centauri but, also
the nearest GALAXY to us, outside the Milky Way.
IF abiogenesis is possible, we and all life from earth
came from the stars.
The earth was seeded. Period. That's how life on earth
got started.
