For the sake of argument I'm going to agree with the motion. I believe that life originating on earth is plausible, given that we can simulate significant entropy and watch RNA self-assemble in a state that resembles early earth...

But a good point made is that primitive bacterial life forms can survive for months exposed to the vacuum of space. This demonstrates that early life is, for whatever reason, adapted to space. One explanation could be that life came from space. I'm not merely saying from Mars, but in the long solar history there are plenty of nebulae out there which this solar system would have passed through. If life evolves in space, there could be such places just fertile enough for life to evolve and then hitch a ride on planets, dying most of the time, and thriving occasionally on planets like earth.

A counter argument could be made: since life thrives in our upper atmosphere, and since early earth conditions would have been significantly more volatile, life could have thrived early on in the atmosphere rather than on the ground. The proximity to space is close enough that theoretically life may have been exposed to, even surviving briefly, in the void just above the planet.
