Consequent Infidel

I'v been into learning about cosmology and How can it occure Without a cause/creator ,but I'v been having some trouble getting into the details of the big bang because I'm Not quite well informed in Physics , so, I thought i would ask these questions here ;

1- Was there any kind of "existence" before the big bang occured? - did energy exist before the big bang?

2- what Caused the explosion without a creator or another "source" / where did the explosion energy come from ?

3- If there was no existence of any kind before the big bang , how did matter come out of "null" without a creator ?

1) Probably not.
2) Nobody knows. One theory is that there is no total energy. The entire universe, if you add it all up, would amount to exactly zero of everything. Past that I have no idea.
3) Beats the hell out of me.

Science can take a stab at what happened way, way, way back, up to much less than an atosecond after the Big Bang, but before that it's pretty much unknown, and possibly unknowable.

The answer to all 3 of your questions is: we don't know. The standard Big Bang model has nothing to say about causes or priors. Read all about it here:
