Greetings, I have heard by many that the beggining of the universe was a result of the big band and now I also get to hear that we don’t really know how the universe seize to exist and there may be existence of the universe before the Collison itself thus are not certain if the big bang is the beggining of time.

So that arises three questions firstly why would you think that there is something before big bang even though all the evidence we gathered sum up in the favor of the big bang theory? And secondly how do we know that the universe even has a start and an ending? I am religious and do belive in a creator so that makes sense to me but how do non believes think the universe started and why do they use phrases like “the universe has a brain” or “… The universe can think” and even weirder that some belive in aliens, the existence of Extraterrestrial beings, yet still don’t belive in a creator? Isn’t that kind of ignorant.
