Where did the Big Bang Come from?

[Cyrus]

Sometimes the world seems so huge and full of miracles in even the tiniest things that you get this overwhelming feeling of never being able to comprehend the world you're living in.
For some people this may lead to accept the concept of a god.
Probably because all of this stunning world around yourself seems impossible to be originating from random events without any guidance of a `higher` power.
For me this power is nature itself, which we try to understand better by researching it. Even though we probably never will understand it to the deepest origin.
And science is nothing that explains nature but merely describes it. We can learn about gravity, qed, qcd and so on. And those studies help to describe the world and create tools for us. But it doesn't explain why there is gravity and so on to begin with.
To make it short i don't know where our universe originates from but it's fun to philosophy about it.
But religious beliefs, whether your following the Bible Quran or whatever, seem very silly to me. They are just stories written down by other human beings who couldn't know themselves. Those books are not more likely to be true than any other story.
Of course one might argue that the books have been written by humans who received the word from god himself, but why would you trust in that?
Looking at human societies and how every growing empire tried to bind as much power as possible and will lie for their advantages, how can one possibly trust that those messages from god have been passed down over countless generations without ever being manipulated by those who could find advantage in doing so, like every king ever who claimed he's the rightful king under the name of god?
I can't see no possible reason of why a god should exist.
Of course i can't know that for sure, but then again it seems just very unlikely, so why should i belief in something just because i can't disprove it?
