I don't believe religious stories and myths were made up from people's heads. They are long diluted and misinterpreted histories. At some point the idea of gods emerge. From what history?
Many creation myths and epic tales of religions describe natural phenomena as the work of gods. The great flood is mentioned in countless world religions. Around 8,000 BCE the Pleistocene ended with the melting of the glacial sheets. Sea levels world wide rose hundreds of feet. Every coastal community in the world would have been destroyed and submerged. The Bahamas were one island, as were much of the Greater Antilles. The land bride of Beringia was much more than a bridge, the continents connected with a strip of land the same breadth as Alaska. The British Isles and Scandinavia were one with Eurasia. Australia and New Guinea formed one land mass known as Sahul.
But what of the godly characters that are implanted in this true event? Were some being actually at work here, snatching up animals? There is so much tantalizing evidence, but all so futile.
Imagine a future in which we might peer into the past to fully know ourselves. Imagine a trans-dimensional astro-projection into another time. Ghostly observing life.
