No argument on either side is particularly logically persuasive, so the best we can strive for is plausible.
Something akin to "Dust Theory" from Permutation City is a semi-plausible theory of non-creation (although, as it's fiction and must at least pretend to entertain a plot, some happenings in the book are much more far-fetched).
Edit: although on second thought maybe the book's actually more of a theory of creation, and we're the insects. I don't know.
Permutation City's dust theory was the first idea that made me think: oh maybe something like that. It ties in with the whole "why isn't there just nothing" - total nothingness is a state as well. Probable, coherent states "exist" (maybe).
I think a better question than "who made us" is "where are we?"
