It should be clear by now to all but the most die hard hyper skeptics that our world is not what it appears to be. Skeptics have the most curious ability to ignore the evidence that mounts daily pointing to advanced technology in our ancient past, right up to today. I cannot say that the glyphs represent helicopters and UFOs, but it seems to be more than coincidence. Skeptics can explain away the glyphs, the delta winged "incense burner" from Peru, crystal skulls, skeletons of giants, UFOs, and a host of other phenomena, but at the risk of their own sanity. In a universe of multi-dimensionality, super string theory, folding of time and space, and the oneness of all matter, I would be just a little nervous about making bold pronouncements regarding what the ancient world had experienced. It is not necessary for the ancients to have possessed the technology, they merely had to see it. What if this stuff came from a parallel universe? Go ahead and laugh, but they laughed about big foot. Who's laughing now. Really, if Occum's razor is in effect, then these things are what they appear to be. Duh.
