Author and world traveler Graham Hancock continues to launch thoughts that go bump in the night. A dogged explorer of human evolution and civilization, Hancock weighs global commonalities in ancient petroglyphs. The motifs and patterns reoccur, oceans apart, showing identical images, patterns. How is this? Hancock presents a considered thesis - ancient individuals, entering altered states of conscious via drugs, witnessed the same spirit world. Thus a man in South Africa would describe the same other-wordly landscape/beings as would an ancient in Southwest USA, or France, or Australia. I can't think of any people whose ancient history does not include a free-flowing interchange between this world and that world. Perhaps such interaction was more common and personal in times past. Perhaps use of certain drugs affect DNA in such a manner as to become a "radio" tuner aligning frequencies, permitting the "man" to listen in, see, and perhaps even participate in the spirit world. Who knows? Shortly before his death Nobel Prize genius Crick admitted that he was high on LSD when he saw the DNA double helix. In this modern case, he certainly returned with knowledge, gained from, well, somewhere.
