Believing in an imaginary being such as a god or any other supernatural being is a human psychological flaw. Every human needs answers to it's life's questions. Combined with the human lazyness you come up with a concept like a supernatural being(god, allah or any other wise guy) which you attribute all the answers to so you don't have to come out of your comfy chair to look for the answers yourself.
Also god or any other supernatural being is comparable with imaginary friends children often have. Because children who have imaginary friends develop them because they are less assertive than others and thus have more difficulty to face the world alone. They need this imaginary friend to guide them through this hostile world.
