The question of truth has nothing to do with a gland. Last time I checked, Angels have no pineal glands, were made perfect and yet a third of the angels believed a lie and were thrown from heaven... no pineal gland, no poisoning and no fake news. Humans were deceived by the serpent who said "you shall become like God". The second oldest religion is humanism where man wants to be God! We want to be the measure of all things and we want to believe we control our fate. Pineal glands and "third eyes" are pseudo trascendent ideas posing as religious truth. Deception existed prior to flouride.
