Dr. Michael Persinger, who is a neuroscientist, developed a theory of neurotheology during the 1980's which provided evidence that 'God' does not exist outside of our minds; even though people believe the 'God' created us all. To prove that 'God' does not exist outside of the mind, Dr. Persinger artificially simulates a religious experience by stimulating a small group of brain cells located on the right hemisphere of the brain in the Temporal Lobe by activating a magnetic coil. As the electromagnetic waves affect the temporal lobe, the participants report feelings of a presence, visual sensations, meaningfulness in life, fear, and even a sense of leaving the body.
