I mean, of course you can't get a direct/clear answer to life's "big questions". But you can explore some of the works of ancient philosophers such as Socrates, Aristotle, Plato etc. Their theories about such questions definitely provoke some intense thinking. Or you could just study science. It offers some more... "Logical" and less fantastical ideologies as to how the Earth was created or other things along those lines. I hope this helps!
