Hello All,
The word coincidental carries with it the sense that when things occur together, or within a certain time frame, that they are not necessarily related events. But, for this thread, bringing in an adaptation of the word is key to understanding the position of the idea presented. So i'd like to introduce "co-incidental" to describe the point that events actually ARE related. For starters:
At 40,000 years BP (before present) these things occurred:
1)The geological record shows an extremely large spike in beryllium 10, the isotope created when cosmic rays interact with Earth's atmosphere.
2)A very large eruption in the Phlegrean Fields (southern Italy) of what is called the Campanian Ignimbrite took place.
3)A dramatic deterioration in the climate of at least that hemispheric region in addition the Laschamp excursion in which a geomagnetic reversal took place,
4)The Heinrich Event 4 (HE4) which was the fourth of six floating-ice-shelf periods evidenced by rocks in the seabed that were dropped when the ice floes melted.
5)Water levels before the warming were about 100 meters lower than today allowing for coastal settlements which were later inundated.
6)The migration of Cro-Magnon peoples into the European continent (was occuring with the apparent advantage of having language).
7)Neanderthals which had been on the European continent for 90,000 years (themselves becoming extinct 10,000 yrs. later) were losing there habitual food supply (meat) due to over harvesting and hyper-concentration as a result of reduced land space. The animals they depended on for food and shelter, along with Neanderthal, were being squeezed into southwestern Europe by glaciers and the advance of Cro-Magnon.
8-Weather patterns also possessed a split jet stream causing more cold across glacial regions tying up more moisture and leaving the more inhabitable lower latitudes suffering in prolonged drought which had stimulated the north migration of Cro-Magnon in the first place.
All in all, the stresses imposed by nature, competition for food and
space, and conflicts created and environment at risk for disease and self destruction. If there was an oportunity for extinction this was a major senario. Then too, the evidence of a concentration of beryllium 10 in core samples indicates that a cosmic superwave struck the Planet as well.
Not a very pretty picture IMO and if ever Believers in ancient Alien presence and aid wanted a situation that called for intervention this would be a prime time for it. It also would be a fine example of what this thread is attempting to convey. For some this may not be a good enough argument for a rescue senario but at some point the Human population of that era also experienced a tremendous surge of creativity along with an advance in tool making and, as mentioned above, language. Gradual processes of contact with ET?
However it's a good theory nonetheless. And for ancient-Alien proponents looking for a solution for current UFO presence, this at least could make for some very interesting and thought-provoking discussion WRT the many points of the co-incidental factors mentioned. It is a good argument for "why" ET might be here. These past events no doubt witnessed great Human suffering and placed the Race at great risk for our extinction.
After this time period there was a sudden shift to warming which presents it's own set of dynamics as one can only imagine. It's diffucult to imagine what it must have been like. In the warming cycle the tectonic actions created volcanic activity along with earthquakes as a result of the great weight of ice being removed from the land masses. As fresh water got dumped into the oceans over time, stopping their currents, the cycle would repeat.
I'm now working on the next time period.
