God isn't real discussion?

Lets take for example the power of prayer. Its a win-win situation for believers. Whenever a prayer is answered, they jump about proclaiming the joys of god, but when a prayer is ignored, they jump about proclaiming the mysteries of god. God was created by man. Everything we know about god was formulated by man. So how can we know what god wants from us? All we have is word of mouth, and people are dedicating their entire lives to these sentences written on paper about a supposed being that wants them to do these certain things and will reward them. When you really think about it, its absurd. It just seems like some religious people will believe more in these stories than actual scientific facts. I bet if I wrote some nonsense down now about how I created the universe and spread it amongst the populace I'm certain I could find a few followers. And hell, maybe hundreds of years later other people will have forgotten how stupid it sounded and follow it too. The fact is, there is no evidence of god. I believe there are about 3,000 known supreme deities, all of them stories which have fallen in and out of fashion as time progressed. The gods we worship today are pretty much the remains of an extensive oral and written tradition which originated thousands of years ago, in a time when people were really gullible. and i mean really gullible. Whenether we don't all stray away from faith is beyond me, maybe some people need to have this comfort in their lives, maybe some people are afraid to realize that maybe they themselves hold the power in their life, and that there is no watchman up in the sky watching their every move, rewarding them with stupid things like money and fame while others starve. I personally thing religion is needed in this world. it keeps people in line, and establishes a moral ground. While I agree maybe one day we can finally toss aside this raft and get to the other end of the river, the reality is religion is going to be around as long as humans can come up with this stuff.
