God is created by the brain and can also be destroyed by the brain. But this way ‘Love’ doesn’t exist either, because it also is the result of molecular interaction within the brain. Love is a result of complex and mind-blowing interactions between neurotransmitters like Oxytocin, Dopamine, Serotonin, Endorphins and the reward center of the brain. Does this mean we should downright stop loving our family or friends? Since there is no existence of actual ‘Love’, should we just deny what our heart feels for our beloved ones? Whatever the answer is, the same goes for the faith upon divine existence. Only one thing to remember – Love gives life, so should faith.
