The Big Bang happened, there is no question. If it did not happen then physics and math as we know them are entirely incorrect. The events prior to the Big Bang are what is being called into question, the religious value an idea of creationism or divine causality, scientists value the current hypothesis among cosmogonists.

There is a date for the universe.
So what was before the big bang?
If you choose to approach the question from the cyclical perspective then our universe existed before the Big Bang, from a string theory perspective there existed a large amount of false vacua (10^500).
