Are you saying that in order for me to believe in evolution I must believe in abiogenesis? Bearing in mind there is no scientific consensus about the origin of life, what exactly do you think I must believe? I honestly have no idea what you're taking about. How did we get the diversity of life we see today and in the fossil record? Evolution. We have massive amounts of proof. How did life begin? Not sure yet. But now we're on a different topic so whatever the answer it doesn't have any bearing on evolution. It's like claiming that everything we know about gravity is wrong because we don't know what caused it in the first place (although we do have that answer now). It doesn't affect what we can observe and the predictions we can make just because we don't know why the phenomenon exists.
