I don't exactly believe in a supremebeing, but I don't excuse the possiblity either. Why? Because there have been things in life that have convinced me that science as we know isn't all. And though I believe that spiritualism may both be true and false, over the years, I'm convinced it's true, but I still keep the fact that it may be false in mind.
I have to stand up for religious people for a bit, though.
When religious people pray and such, it's not like they're asking for an answer, but actually for a feeling to see if it's the right thing (for them) to do. It's not like god (of any kind(s)) is going to leave a sign on the refrigerator note saying "Yeah, start up that business," but more of a feeling you get; an intuition.
Many don't even know what they believe, however. Some were born into the religion, some found (or refound) the religion on their own. Those who sought their own generally understand the belief better. Those who grew up with it and, though, think they've been doing everything just fine, when their belief somewhere strayed from their religion itself. That could be due to the cause of anything: parenting, peers, trauma, ect.
So for what you believe (even if what you believe is that there is no god of any kind), just keep an open mind, yet hold your own. Look for it yourself and the truest belief and faith you'll have is yourself.
(at least that's what I believe

)
EDIT
Oh, also, for ThE_tHiNg, I havn't done anything for you, do you believe in me?

And have you done something for him first, like praying or offering (depending which religion you are trying to learn about and give a chance to believe)?
And no one has PROVED how the world began, they're all theories and hypothesis.

That's an exaggeration (well, it is since you're speaking of Christ). Let me ask you this, if you had died and a million years past, should we not believe in your existance or question it?

"no offense to any1 but if there was a god he is not mericiful theres alot of pain suffering and death and maybe its not gods fualt maybe he cant fight the devil?
why is there a devil anyways?"
I'm assuming you're speaking of Christianity. All these sufferings and the world and such is suppose to be a test. God and the Devil had a war over difference of opinions (of how humans should live), and a war broke out between the two. Those who followed the devil were casted into the outer darkness while those who followed God went through a Veil of Shrouds (forgot its actual name, but it's a cloudy area that makes you forget everything) and were given a physical body. The physical body, which is somewhat of a reward, is precious and the Devil wants it, that's why he uses his demons and trickery and temptations to gain your body (posessions and such) because they don't have any.
We are on Earth because we were given a body, but must be tested again to make sure we all had faith in God (kinda makes you wonder there, what, doesn't he have faith in
us?) and so put to this test.
Since God won the war, we were able to have free will, as in we choose what we want to do. The consequences, however, are our own to handle (or in some cases, of government officals' >_<)
Either way, God doesn't jsut DO what he wants to do. It's not a videogame with insane cheats. And all these sufferings? Well, don't you think that's really more of the cause of Man? And, instead of worrying about all that suffering, why not do something to help it? We can question it all we wont, but with no actions taken, the thought wont be counted there. Also, suffering is a lot more than just war, death, plagues, famine, ect., suffering may be as small as a child being bullied in school or domestic issues in certain families. All these are sufferings, and no one can really discredit them as sufferings because everything hits us at a different magnitude, saying something that happened to you is a lot worse than somethign that happened to me may seem obvious, but not necessary always true.
Again, stay open minded and be ready for all possibilities.
