As usual, I will beat the drum for Velikovsky again.
...so many major climatic, seismic, volcanic, and who-knows-what-else changes...
Read Worlds In Collision and Earth In Upheaval. Perhaps the catastrophes of 3,500 and 2,700 years ago helped bury the fallout of the apparent nuclear wars, spoken of in the Vedas, or whatever corruptive fallout from misused energy systems that Edgar Cayce told us of that helped bring the fall of Atlantis. Without the extremes of the several global destructions V. told us of being considered, and under the scheme of Uniformitarianism, after the Charleses, Lyell and Darwin, our dating methods and biases lead us yet farther astray. Our forebears tried to tell us what happened. They tried so hard. As psychiatrist, Velikovsky has diagnosed, we suffer from "collective amnesia." They wrote it all down, but in two to three generations, natural history started becoming myth and metaphor.
North America and Northern Europe were still covered by massive glaciers at the time...
And yet, when we circle these latitudes 180 degrees, what do we find? No evidence of glaciation in the same epoch at similar latitudes, but if we travel north from there, flash-frozen mammoths with temperate plants frozen in their mouths! When will the most recent ice age myth be seen as evidence of a more recent axis shift? Look at the glacial lakes of North America, going all the way up to Great Slave and Great Bear Lakes, and down through Lake Winnipeg and the American Great Lakes, and you can see the old Arctic Circle, scraped into the Earth's crust.
From what I see, using my sources, humans have slipped their own nooses before, but it took cosmic catastrophes to allow a few Adam and Eve scenarios here and there, and not human cleverness, to do the job.
So, when is Nibiru getting here? Is this why so many of the world's top politicos have been visiting Antarctica of late, to see the incoming planet, visible only from the far south?
