>>12982891Don't let the language associated with the term "Big Bang" fool you; the confusing semantics of what the word "before" means prior to the creation of time and space, this is a perfectly reasonable question to ask.
We do not know for certain that the big bang was the creation of *anything*, let alone everything. Some theories hold that the big bang was a phase transition of spacetime, not the creation of it, and they are hardly unique in their interpretation of what the big bang was.
Our mathematical models are only approximately correct, and they do not allow us to extract useful or meaningful information prior to the first moments *after* the big bang. We don't even know what a more complete theory will tell us about the instant of the big bang (if such a thing exists), so it's anyones guess whether or not the theory has something to say about "time" before that.
