well, one of the leading ideas about the whole start of everything is the casimir effect, in which dual virtual particles appear out of the vacuum of space, and some physicists believe that this triggered the big bang, but I think there has to be something more to the picture than that. There are things which we as 3-dimensional beings cannot comprehend, and I think that a lot of that stuff is just beyond our limit of comprehension. Still, that's no reason to not theorize and research and learn as much as possible about the beginning of everything. I think there is some sort of guiding energy or something beyond human understanding that holds the key to the reason behind existence.
