interesting article - thanks for sharing.
There seems to be a deliberate cover-up of ancient civilizations who were much more advanced than us for example the Pyramids or descriptions in the Bhagavad-Gita and so many other examples around the world. I wrote article about the different categories of evidence with examples here but I agree we really need to study this topic in depth without any pre-conceived ideas. IMHO the universe, like the sea, is teeming with life!
