All that does is push the question back, if life on earth came from another planet, where did that life come from and so on and so on, untill you get right back to the orifinal lifeform, where did tgat cone from, so the panspermia theory is a meaningless idea, it just pushes the question of how life came about, further back
Not following here. Straa is saying that evolution, whether or not including possible panspermia, is worthy of acceptance. The Big Bang only serves as a possible limit on how long it could have gone on. I note that apparently life on earth has gone on for maybe 4 billion years, and that's about a third of the time since the big bang. Three times that length of time is not going to really make the case for abiogensis being that much more probable. Plus there is time to communicate life between distant planets or life sustaining places. More likely abiogenesis occurred in many places as soon as conditions were right. Might even have occurred here several times.<quoted text>
I thought there is an answer to that. The Big Bang.
