Do you know how long 3.5 billion years is? Can anyone really grasp such a huge number? I can't accept evolution as fact because there is no proof that it's fact. There are tons of fossils, lots of evidence of what happened, with some pretty good evidence of when it happened, but practically nothing but raw speculation, ever changing, about how it happened. Creation is an obvious answer; if a thing exists, it must have been created. We know that hydrogen didn't evolve, that it was somehow created. We know that sub-atomic particles didn't evolve, that they were created. We know that all the evo theories of how life began have never been recreated in any lab, despite some very earnest tries. Things that exist were somehow created. That leads me to believe that there is a creator. This simple logic has yet to be intelligently refuted by evolution apologists. Tell me how the first bits of life came about. Then show me your proof. Tell me why, if simple organisms can spontaneously pop into existence, that more complex organisms can't also pop into existence? How do you know that species didn't just show up, whole and unevolving, all at once? For all science knows, our creator is still creating different species, all the time. The evidence for evolution fits this perfectly. And you wonder why folks question your theories.
Who created the creator? After all, if something exists, it must have a creator.
I think your first clause disproves yours second. We know how it happened: selection, mutation, gene flow and genetic drift, and we can readily and repeatedly observe those four forces in the fossil and genetic record.
We know that hydrogen didn't evolve, that it was somehow created.
I don't know what "evolve" means in that context. Evolution in the biological sense refers to a change in allele frequencies over time. Hydrogen has no alleles. It did not "evolve". Hydrogen did form approximately 300,000 years after the Big Bang, per cosmologists, when atomic nuclei and electrons cooled down enough to combine.

My answer is: I don't know. Evolution has nothing to say on the matter -- as far as I know, God could have created the first life.
