Excellent, very glad you're interested. I think its an important topic for humanity just now.

Well, nobody's saying abiogenesis didn't happen at all, I'm just saying I don't think it happened on Earth - or not just on Earth anyway. Let's propose that life did arise in an evolutionary process of natural selection acting on self-replicating, self-complicating molecules. If this happened then either

a) It's not an unlikely process. In this case it may have happened on Earth, but will also have happened all over the rest of the universe as well. Therefore life will be widespread in the universe. Or...

b) It's extremely unlikely to happen like this. If that's the case, it would only have had to happen once in the universe (without a doubt NOT on Earth), but has then been spread here by panspermia. Once agin - life is widespread in the universe.

And that's what I find exciting - either way the universe is teeming with life.

There may of course be other explanations, but that's for another day!

Yes, absolutely we need to be out there in space finding answers to this stuff!

Cheers for your response!
