Basically a great world scale flood is mentioned in the ancient mythology of a vast number of different separated cultures on different continents, though this is not accepted by most of todays scientists I will in this blog entry explore the possibility of a real global flood and how other theories like crust displacement, the wobble of Earths axial tilt and the accepted known asteroid strike on the North American continent 13000 years ago would fit into a thesis on a rapid global scale flooding, as partially described by our ancestors.
Rapid Crust Displacement Theory and Pole Shift
Not to be confused with magnetic polar shift which does not involve any actual change of the crust and locations of the poles but a switch in magnetic polarity causing the magnetic north and south poles to switch, as seen in the geological record of the magnetic rocks in the crust.
In this theory the during the end of the last ice age the glacial ice cap that covered most of the Northern Hemisphere land-masses became so massive that it caused the crust of the Earth to shift, causing all continents to shift in position compared to the liquid layers of magma that Earth's crust float on-top of, this shift would caused the European part of Eurasia shifted more south and with the Asian parts like Siberia moved closer to the North pole, shifting the continent of Antarctica making it totally covered under todays South Pole ice-cap and this shift are also theorized to cause massive earthquakes and wide spread tsunamis all over Earth, and thus being one possible origin to the global flood myths. (Read Cause and Dangers of Tsunamis for more on tsunamis)
This theory should be simple enough to prove or disprove based on Earths known hot spots like the super volcano of todays Yellowstone Park, and the hot spot that fuels the volcanos of Hawaii, with a shift in crust these hot spots would shift location compared to the crust since a hot spot are anchored to the deeper core of Earth and do not follow the crust movements but punches holes in Earth's crust as it passes over the hot spots, causing new volcanos to form like the chain of the Hawaiian isles that one can follow as a chain of ancient volcanos past Midway and even all the way up to the isle's of the Bering Strait.
Earth Has a Wobbling Axial Tilt
The Earth's wobble is widely accepted in scientific communities, this wobble is used as one of the current theories to explain how ice ages and interglacial hot periods like the one we are living in now fluctuates over millions of years according to Earth's axial tilt. The axial tilt controls how much solar radiation and seasonal variation the different parts of Earth receives, the farther away from the equator of Earth one are situated, the greater the effect the axial tilt have, according to this theory Earth's wobble changed slowly over time and thus should not cause any rapid changed like a global flood, though it would cause coastal lines to emerge up dry and submerge as the waxing and waning glacial and interglacial cycles troths along.
Approximately 13000 years ago an asteroid hit the Glacial Ice of Northern America
In the end of the last ice age, there are evidence of a rapid change that caused a miniature ice age to cloak Earth for a few thousand years before it returned to the hotter interglacial climate that we still see today. Now this impact event was big enough to almost instantly melt a large portion of the glacial ice that was still present in Northern America 13000 years ago.
This same impact cloaked the Northern Hemisphere with a large amount of dust blocking out the Sun, causing rapid cold to overtake Eurasia, and some parts like Northern Siberia are still kept colder than it was before the event happened 13000 years ago. This also caused a large amount of low laying land and coastal areas to turn submerged within a short period of time, it also caused a swift change in the ocean jet streams that regulate how much hot and cold water are shifted around the Earth, causing Northern Europe to turn hotter while Northern Asia like Siberia turned colder, and this is still in effect 13000 years later.
It also would have changed the heat conversion in the Southern Hemisphere possible causing Antarctica (which some ancient world maps seem to depict in detail according to its still glacial ice covered coast lines) to turn even colder than it was back 13000 years ago until this day, also in addition to flooding low laying islands and costal areas on a global scale.
The asteroid impact very likely also triggered a lot of Earthquakes that could have added tsunamis to the global serial floods, and possible be the origin of the worlds flood myths.
To conclude
So my personal opinion and suggestion is that even though an asteroid strike could possible but unlikely also caused a crust displacement, and larger than usual change in axial tilt of the wobble, it could alone have been the smoking gun that proves that our ancestors actually did experience great floods before the time of written history, and this was carried on for generations before they finally were placed in stone and other media of writing.
