yes,it's a theory based on some studies of astrophysicists and cosmologists...
and i agree that it's very theoretical, it's just a point of view ,because i think humanity will never know the absolute truth about its origins...
I think our Creator ,for a reason we will never know ,made our brains very "primitive" ,so we will never understand or discover our origin and we will never find the answers to our questions about our existence...
Maybe God is the energy that made the Big Bang happen :)
