Let's examine existence without God...
Without God, there is no primal-cause for existence. A primal-cause is, by definitive default, the only determining factor of existence. Such a cause has no external needs or influences in the creation of effects occuring within it. If we apply reason to the term "primal cause", it soon becomes apparent that we are in fact talking about God itself.
Hence, without God, there is no primal-cause within existence.
The absence of a primal-cause means that everything in existence is an effect. Who amongst you wants to defend this absurd position? I'll wait for rational responses. If none are forthcoming, I shall destroy the position anyway and show you that there is a primal-cause = there is a God.
What caused God?
Why doesnt God need cause?
What makes God the primal-cause?
Your logic is very circular.
(Note: No offense to deists.)
But to answer you question:
Here's the short answer (much hand-waving follows):
First, the Planck length. Max Planck discovered that there was a number (a very very very small number) which was effectively the smallest thing you could have. Expressed as distance, the Planck length is the smallest distance you can measure, like the limit of resolution of your ruler. Expressed as energy, it's the smallest bit of energy (the so-called quantum). Expressed as time, it is the smallest bit of time you can measure. (Remember that time and distance are functions of each other, so the smallest distance and the smallest time are related).
Then Stephen Hawking discovered that underneath this limit, all sorts of hanky panky was going on. For instance, sometimes particles (like say an electron) will just appear out of nothing, for no reason at all. So the old adage that something cannot come from nothing is false: it happens a gazillion times a second.
Of course, you are wondering, why don't we notice this? Well, its because the universe is as bad as a bank: you can't take money out without putting money in. So when that electron just pops into being, an anti-electron is also created. And here's the kicker: the two of them wander around a bit, and then collide. Well you know what happens when a particle and an anti-particle collide: they both go woosh! And the energy they create from their explosion is exactly the same amount of energy it took to create them... so everything balances out!
But wait, you say. Wouldn't we notice all this wooshing? The answer is, all of this takes place under the Planck limit. So no, we don't notice it. You know that movies are really just still frames displayed really quickly, right? And because your eyes can't adjust faster than 30 times a second or so, you can't tell. You don't see the stillness, just the motion. The Planck limit is like that: you can't see well enough to see the individual actions, just the net result.
So... imagine the universe when there was no matter in it. No distance, either (and hence no time but that's a different issue). Nothing at all. So along comes some innocent particle, pops into being just like they always do, but wait: there is no distance. Well you know what happens when you stuff 20 lbls of potatos into a 5lb bag, right. No distance means that the first particle had infinite density. Infinite density means infinte mass, which means infinite energy. And stuffing infinite energy into a tiny point means kaboom!
And there's your Big Bang. Out of nothing. Of course, now that we have distance, we don't have infinite energy anymore. So all those little guys popping in and out don't matter so much. But they still serve to evaporate black holes, so we're grateful they're around.
