No, as we humans are, we cannot possibly get understanding of everything in any amount of lifetimes, unless there theoretically was external help (from "God", or "aliens", or whatever the fuck (but if you firmly believe in any of those you're an idiot)).
And about fictional explanations, that's what gaytheism and all this evolutionary bullshit and Big Bang stories and whatnot are, except they're presented with a "scientific" and "objective" coat of paint, while at their core, they're as true (false) as religious stories. But again, at least religious stories have the merit of being interesting, while gaytheist ramblings have this "scientific" presentation that makes them as interesting as studying what a mitochondria is in middle school.
