"I don't know" =/= dirt
evolution =/= abiogenesis
evolution =/= The Big Bang
abiogenesis =/= The Big Bang
I'm assuming that by talking about talking about "what was the first thing that came into existnce before the atom" he's talking about the origin of matter. I think he's talking about the start of the universe as we know it. So I'm going to be generous and assume he's talking about the Big Bang, but simply doesn't understand anything about it.
But simply put:
cosmology =/= biology
In any case, even abiogenesis doesn't say something as simple as "we came from dirt". The Bible on the other hand . . . well, what was it God made Adam out of again? Wasn't it dust, which is basically, you know dirt.
Anyways, what we're actually looking at is:
ignorance vs. evidence
"I don't understand and you guys say you don't know, so Goddidit!!!" vs. "We don't have enough evidence. We don't know, and it would be wrong to pretend we knew something that it is impossible for us to know."
