A distinction:
Evolution is the theory that all life forms on earth descended from one initial organism. It doesn't make a statement about, nor even care, where that first organism came from.
It's the theory of
abiogenesis (literally "life from non-life") that states the first organism came about from naturalistic processes.
So evolution doesn't "require" anything of the sort.
If you want to read a really good rundown on abiogenesis, here's a link to some FAQs:
