Why are so many people religious?

I don't know if it's just because of where I live, but practically everybody I know is religious to some extent. I don't understand this! It is sooo easy to see all the fallacies in religion. I am willing to accept it if I am missing something, but I seriously can't find any loopholes or reasons to believe that any religion is correct. Are these people just in denial or lying? Am I the one that is really uneducated on these matters? Or, are most people just that ignorant? I really want to figure out the truth, whatever that may be. I can deal with it. Please, I am not trolling here. I really cannot fathom why so many people are religious. Can somebody explain it to me as objectively as possible?
