Support for Muller's Theory on the Origins of Religion

Friedrich Max Muller's work on determining the origin of religion was done primarily by comparing religions. He sought to show how religions stemmed from one main concept. This process of comparing religions, however does have its limitations, but perhaps it did provide Muller with some insight into the matter.
According to Muller, religion began in the human mind. He claimed that we, as humans, have always had some suspicion or sense of the Divine. What I find most interesting about this theory, is that there are recent scientific studies to support it. There are some scientists who claim to have found a gene on the human DNA that relates to a person's ability to believe in a higher power. Whether this claim is correct or not, I cannot say but it certainly raises some controversy. There are many who feel that such a gene would completely undermine having faith. Others (myself included) would view this as evidence that God exists and desires us to seek Him. In either case, as carriers of this DNA, we would surely feel dependent upon a higher power, as Muller suggested.
The question of how religion began, like many others in this world, is one that we will probably never be able to answer definitely. Yet the search for answers continues perpetually. We are on a never ending journey to answer life's deepest questions.
