I never said that.
What I said.
I didn't say that.
I said you can prove it to the extent that anything can be proven. It's a scientific hypothesis at this point. I think it's currently the best theory, but I'm not convinced of abiogenesis. As for if it as random or not, I haven't seen any proof that it is not random so it is logical to believe it is until proven otherwise. That has nothing to do with faith.
