Doesn't the idea of a Big Bang contradict the idea of a universe?

THE BIG BANG IS NOT POSIBLE BECAUSE THE UNIVERSE WAS EMPTY AND EVERY THING NEEDS TO BE CREATED, AND EVEN IF IT DID HAPPEN EXPLOSIONS DESTROY STUFF NOT CREATE IT, AND EVEN IF THEY DID ITS IN A VAE AND ALL THE "STUFF" WOULD KEEP ON GOING FOREVER.
