Could there be a chemical god?

The brain is a very active organ, even in sleep the brain can give you dreams and open up the imagination of what you have seen in life, learned in life, and experienced in life. When a child your brain is like a sponge, you take in all you see and remember it in your brain including all the things your parents teach you about life, you know no different then what you have been told. So naturally a Christian parent would want their child to do the same as them, same with a Muslim child, and the surroundings of what everyone in that area find morally acceptable. So if you have been told at a young age that everything that is good is the work of a God, you will link that to what your brain is feeling at the time, and the emotion you felt when the event happened. linking this emotion to the God that you were raised with from childhood to adulthood, and the religious texts your parents have brought you up with, will no doubt affect the way you view life. Our brains are chemically functioning organs, and release these chemical's based on our situation at the time. Would it not be possible, as people have been brought up linking the good emotions and the bad emotions to their particular religion, believe in a God/God's because they still link their emotion to a God?
