If the universe has enough mass, its expansion will slow and it will eventually contract into a Big Crunch, only to explode (bounce) outwardly again. An oscillating universe like this could have gone back to negative infinity. It was always here - there was no beginning of time.
Astronomers are still trying to determine if there is enough dark matter in the Universe for a Big Crunch. At the moment, it looks like there is not, but nobody knows for sure.
Perhaps God always existed and there never was a beginning.
God or Big bang? Fake?
