I can't answer every question especially pertaining to evolving science. I wouldn't even try.. I'm not religious either. To have something, someone or something had to create it that's all I can muster on the subject. Can you create anything without touching, moving, manipulating by some outside force?
I don't know how it happened, why, person or thing. All I can figure is if the universe was a blank sheet of paper, something had to add, kickstart, etc a reaction for things to unfold regardless of size, time or scale. I don't really believe the universe at its utmost basic, blank canvas form voided form, simply has energy. It doesnt make sense. Energy requires input from some outside source.
