There was a time, before science discovered more about our solar system, when non creationists, basically were sure, that the close universe would be teeming with life.
What they found, were a bunch of inhospitable planets.
Life from elsewhere, theory, the best at the time, took a big hit.
The further away the proposed, "source", for the plants etc, on earth, the more unlikely
The proposed earth timeline, even taken to extremes, is problematic for the fabled "primordial swamp", and now the distance for interplanetary probability is surpassing sci-fi believability.
Where is the evidence for anything besides creationism?
