“But if you think the human race and all the life on earth evolved because of our conditions here, then it has done it hundreds of thousands, or even millions of times.”
Nonsense. Evolution doesn’t deal with the problem of where life came from, only what happens to life once it already exists. What you are speaking of is the notion of abiogenesis (life arising from non-living materials), which is not a scientifically established idea, but mere speculation at this point.
Exactly! Richard Dawkins makes the same point.
You completely miss the point. If we evolved from an abiogenic starting place, it has happened hundreds of thousands or millions of times.
The only argument against it is the belief that God created us and intentionally did not create any other life anywhere else. And even that is weak, you cannot point me to a bible verse that says God created -only- one planet with life.
