There’s no possibility of an answer to the question because causality is an arrow that always requires a point of departure.
What do you think of the following answer? There is some evidence that backward time travel may be possible under some circumstances in a way that is compatible with general relativity. So suppose, many years in the future, a team of physicists and engineers creates a wormhole in the universe and sends something back to the time of the Big Bang, causing it and creating our universe. That way, it’s all self-contained.
Self-contained is good, though it doesn’t resolve the existence problem. (What is the appropriate cliché there … you can’t pull yourself out of quicksand by pulling on your boots?)
Backward time travel itself opens up a number of wonderful possibilities, including universe self-reflection and the possibility of a post-hoc framework of objective value.

It also makes encryption more difficult!
