Eschatology is the study or philosophy of formation of ideas about the end of things, apparently derived from the Greek ἔσχατος meaning "last" and -λογία meaning "study of".
What is the word for "the formation of ideas about the beginning of things?
Edit: I've accepted "cosmogony" as the answer, but I also really liked "protology". Thanks for your thoughts, everyone!

Eschatology has to do more with the "end of humankind" specifically than the "end of things". So, if Eschatology is concerned with the final events of history, or the ultimate destiny of humanity, then Anthropogeny is concerned with study of human origins.
Anthropogeny comes from Greek anthropo- (human) + Greek -geny (birth, origin).
But, if you want to take it in more general sense i.e. "final events of history", as history1 can be of humans, earth, or cosmos, then it is Cosmogony.
And on the theological side, you can consider Theogony: "the genealogy or birth of the gods."
