There is still too much research needed for the very earliest stages leading to evolution. But I think some of the outlines they are coming up with are on the right or nearly right track.
I keep my options open. Part of the problem is that we don't have rock older than 3.9 bl years or thereabout, a sort of "geological horizon" so to speak. So we are left with trying to recreate life in a test tube. Seems like a daunting task to me but I trust we'll get there ultimately.
