People who are claimed to have the capacity to utilize their third eyes are sometimes known as seers. According to this theory, humans had in far ancient times an actual third eye in the back of the head with both a physical and spiritual function. Over time, as humans evolved, this eye atrophied and sunk into what today is known as the pineal gland. Its been proven by scientific and neurologist that the 3rd eye is located in center part of the brain called pineal gland.
