Atheism vs. God

I have several questions. First, I'll provide the layman's terms as best I can (From my understanding. Please, correct me on my mistakes)

Big Bang Theory
>Beginning of the universe
>Contains a near (if not completely) infinite amount of parallel realities.
>Only exception from that rule(for the most part), would be the Big Bang, itself.

M-Theory
>Primarily deals with the idea of “M-Branes”
>Branes, are unfathomably large masses of energy.
>When one collides with another (or possibly, collides with itself), a universe is created.
>Likely exists in a state of extreme heat.

String Theory
>Protons, Electrons and Photons (which are made up of quarks), exist, but are disintegrated almost immediately in the “Brane-verse”
>The quarks, are made up of strings.

Higgs-Field
>Essentially assumes that these strings exist outside of our conceptions of space and time, and have popped into existence outside of nothing, are everywhere and are ever present.

Questions for atheists;

>What exists outside of this “Brane-verse”? Why do Branes exist? Where did they come from?
>How can strings, pop into existence, in such an intense state of heat?
>Why/how is there an intense state of heat to begin with?

>TL;DR Why/How do we have anything?
