But when the universe began with a big bang, it started out with no elements at all the process now has a name: big bang nucleosynthesis.

I like the response stephen hawking gave to a question like this: asking what was before the big bang is like asking what is 1 km north of the north pole. They proposed that all elements were formed in the big bang models of stars, which end up meaning that corrections here will likely be in the wrong direction.
