Ancient impacts, mega tsunamis and creation myths:

Recently, evidence for an asteroid or comet impact, 4,800 years ago, in the Indian Ocean was found in Madagascar. Huge "chevrons", wedge-shaped sediment deposits, usually containing deep ocean microfossils fused with asteroid metals and pointing toward the ocean were found by the Holocene Impact Working Group, a collection of researchers, scientists and specialists in geology, geophysics, geomorphology, tsunamis, tree rings, soil science, archaeology and mythology from America, France, Australia, Russia, and Ireland. The cause of these chevrons was a mega-tsunami 183m (600ft) tall, thirteen times bigger than the Indonesian tsunami in 2004)

The Fenambosy Chevron, one of four, near the tip of Madagascar is six-hundred feet high and three miles from the ocean. When the Working Group looked for the cause of the chevron, they found the Burckle crater, 18 miles in diameter, 12,500 feet below the Indian Ocean surface and 900 miles south-east of Madagascar. It is estimated to be 4,500 to 5,000 years old.

Though with no concrete evidence for this, to me, this is suspiciously close to the dates when the first major civilizations of the world began their rise circa 3000BC. Climate change has often been cited as a factor in emerging civilisations, but the cause of the climate change has not been known. Were asteroids and comets providing a catalyst for change? Do world wide flood myths have a common basis in fact describing mega-tsunamis? How much force would be needed to create these chevrons and what are their capabilities?

Chevrons have already been found as far a field as Australia, Africa, Europe -including Scotland and the North Sea, North Korea, Vietnam, the Caribbean, and in the Hudson River, New York. So, they are not unknown events. Dallas Abbott, of the Lamont-Doherty Earth Observatory, New York discovered oceanic craters from the chevrons that point ocean-ward, including the Burckle crater. With Ted Bryant, a geomorphologist at the University of Wollongong, New South Wales, Australia, who found two north-pointing chevrons four miles inland in Carpentaria, north central Australia, Abbott was able to later find two 1,200 year old craters, which matched the age of the chevrons. Without trying to postulate a catch-all cause for climate change, extinctions, migrations and myths; asteroid and comet collisions could be one of the most important factors in the formation of human life and civilisation.
