Personally, I have great deal of trouble understanding the concept of God.
The problem is, the simplest of all, and that I’ve been asking since someone first told me about God:
If God is the creator and created everything… how was he created? Did he create himself? How could he?
And that’s about the same question that I make about the Big-Bang. So there’s this whole bunch of energy accumulated, right? But, since in science (to my knowledge) nothing is born and nothing dies, only transformed… from were did this energy came from? How was it formed?
But of course that I’m, as a human being, stupid and only think I can understand what happens around me.
This all only tells you one thing:
Your logic is flawed. Human logic does not account for something simply existing without a cause, and it cannot account for something existing infinitely in itself. These, however, are the only two basic ways in which the universe, or god, or something else, can exist according to our logic. Thusly, our current logic system is flawed.
However, the Big Bang has one nice and interesting explanation:
Before the Big Bang there was literally nothing. Meaning that there were also no laws. And if there were no laws, why would nothing NOT do the whole Big Bang thing?
Now there's a nice twist of the mind.
I have serious problems with the theory of evolution, because it does rest on probabilities to occur and seems too unlikely to me according to the set rules. The possibility of anything happening is minute, as has been said before. But then again the possibilty of the past happening as it did is extremely unlikely. Of course something has to happen so numbers might not always be the right way to study reality. (damn contradictions) Evolution has to be tweaked at least.
This is, sadly, a mistake made very often. It seems extremely unlikely that we, as a race, spawned from evolution. It isn't. The chance that we would exist if everything went completely randomly is minute indeed. However, everything did not go completely randomly, since everything evolved step by small step. Meaning that when a new step in the evolution occurs, only one small thing is changed. If you keep everything that has existed up to that point, and only continue with the good, then the chances are not that slim indeed.
One fault underlying the logic mistake of thinking that the chances are to slim is the thinking that evolution has actually provided for the best possible creatures on this earth, or the best possible creatures up to this point: there is nothing saying that that is what has happened.

(Although the tone is rather annoying, the article has some very valid points. Everyone with questions about evolution should read it.)
