The Universe and Big Bang

[super spidey man]

Ok ,what I have heard is that scientist and physiologists have come to the idea that before the big bang there was nothing and not sure what to think. Correct me if im wrong. and there is ideas a multiverse thing but that still doesn't solve the problem where did the first one come from? black holes and all this other crazy stuff out there had to have a start. and all this stuff that doesn't make stuff to help a mass explosion of physics and laws to happen by itself.
