Why do people have such strong beliefs in God?

I don't understand why people have such strong beliefs in God when it is logical to assume there is no God. I used to be Catholic and I go to a catholic school but in physics I basically learnt that there is no God and the bible explains nothing. Even when I think about the concept I feel as if the human race is basing their beliefs on something that isn't true and has no proof. It makes me angry thinking that and I don't understand how people can just take this belief for granted just because they have been told since birth that is how it is and not question its existance. I would like to know your thoughts on this both Atheists and Religious people.
