I mean I am here to try and learn things that I do not know at this point.
Great, then pay attention and learn.
As for the Big Bang , ect. ect. What caused it .. and yes I assume a "first cause" there had to be one , no matter how far back.
Your assumption is incorrect. The "First Cause" argument (aka: Cosmological argument; aka: Kalam argument) all contain a fatal fallacy that not only disproves them, but in fact proves the opposite of what the argument was attempting to prove.
That flaw is that they assume (implicitly or explicitly) that TIME exists eternally.....and it does NOT.
Time BEGAN at the Big Bang. That was T=0. However, any cause-and-effect argument relies upon the fact that cause and effect are temporally ordered. Cause MUST precede effect. The "cause" must come first. But since time began at the Big Bang, it is IMPOSSIBLE for a cause to have preceded it. "Before Time" is a contradiction and is impossible.
Therefore, the universe does not NEED a cause, and cannot have one, by definition. A first cause is logically IMPOSSIBLE.
The universe MUST be UNCAUSED.
If it all started from nothing, then how?
It's being actively researched as we speak.
Nothing + Nothing = Nothing.
0 + 0 = 0 or even just 0 = 0
But lots of things equal zero. An infinite number of things, in fact.
0 = 3 - 3
0 = X - X
As long as you have "something negative", you can get "something from nothing". In our universe, that "something negative" is GRAVITY. Gravity is "negative energy". It draws energy out of things. That's why it causes matter to clump up, because the matter lost it's energy and cannot escape. That's why it takes a huge effort to climb out of Earth's gravity well. That's why any object moving through space has MORE energy than the same object sitting on the surface of the Earth.
It also explains why matter emits gravity, and why gravity only works on matter. They are linked. A symmetry exists, by necessity. Observations of the Cosmic Microwave Background Radiation (CMB) indicate that the universe we live within is geometrically "flat". ONLY in such a universe could such a thing be possible. This is consistent with (but does not by itself prove) an all natural, ex nihilo, causeless universe.
In short, as a whole, the universe STILL has ZERO energy. All the energy and matter are counter-balanced by gravitation.The Zero-Energy Universe Hypothesis
