People have always asked what happened at the "begining" or a better way to say it where did we all come from.?

the way i see it this question can not be "proven" nothing can be "proven" except "i think therefore i am". however since no on can "prove" where we all come from can't we still use logic based on what see observe to make the best guess? here is the best logical argument i have heard. that since something can never come from nothing and there is something in existence now we can conclude that there is either a circular time continuum (unprovable) or something has always existed. since matter on its most rudimentary level attracts to other matter (gravity) we could say that is matter had existed for an infinitive amount of time leading to now all we would have is one giant pile of mater AKA a black hole. energy on its most fundamental level pushes mater in a direction. and then is turned into motion energy that motion energy would eventually (since it has an infinitive time to do so) be overwhelmed by the gravatical force or matter and there would still be a black hole at the center of the universe. so if we ume time is not circular then we can say that there had to be something OTHER then matter and energy that always existed. so what do u think it is. some people use the cause and effect argument at this point to say that the universe was created. this is often refuted by saying that then there would have to be a creator for the creator. this is also true so basically we have established that the universe should not be possible yet here we are. so either time is circular after all. OR there must be something that defies the laws of matter and energy. aka a divine force. a creator that is infinite and is not bound by the laws of physics. also because non of even this is provable (see earlyer point) whatever we choose to think about the origin of the universe is NOT known it is believed. so my final question is what do YOU belive and WHY?
