"Could this realignment of planet earth around her axis have had an influence on the ancient lake Agassiz in Manitoba, western Ontario, northern Minnesota, eastern North Dakota, and Saskatchewan? Did it contribute to the de-glaciation of North America? This could also explain why we do not find evidence of advanced civilizations in Canada and North America. The area would have been part of the old polar regions and therefore covered with ice. Even the last Mammoths on Wrangle island in the Arctic Ocean became extinct in ca 2000 BC as a result of the asteroid impact". - Alewyn
This supposition is simply incorrect. While Steve's work is (by his own admission) in need of a bit of an update, it should assist you in placing events into an understood time-frame.
"The Oera Linda Book is perhaps the most graphic and accurate record we have today of the catastrophe that hit planet earth and more specifically the North Atlantic coast of Europe and Britain towards the end of the third millennium BC". - Alewyn
Now how does this statement relate to the Burckle "crater", which, again, has not yet been fully proven to be an impact crater and has not yet been firmly dated? Despite Puzzlers proposition, a dating variation of even 1500 years +/- would place both positions as mute.
"4. The thick forest and vegetation cover coupled with dense populations and concentrated cultivation make the identification of prehistoric remains more difficult and expensive than the open deserts of the East". - Alewyn
While this statement may appear to have a degree of superficial validity, it does not display a working knowledge of current archaeological methodology or the results thereof. A study of the professional publications available for whichever geographic area that may be of concern will quickly validate this point. Work with it all the time.
"I agree that the individual pieces of evidence at this stage is not conclusive. I doubt that we shall ever be able to say that there is absolutely no doubt involved. If we,however, try to establish the absolute proof on every single fact, we will never make any progress. What I am trying to establish is the balance of probabilities and then to move on". - Alewyn
One may wish to evaluate this position. I could be quite incorrect here, but some may interpret this to mean that "well, I don't have my facts straight, but just believe me on this".
As a last note - Early on you presented your "findings" as a "dissertation". Given your professional background, one may be led to believe that you fully understand the import of this term. Later you use the term treatise. Ditto. Now it has become a story...
Again, my compliments on your willingness to expose your text to critical scrutiny. Would authors of similar bent be so courageous.
Not that Alewyn would do so (don't know this person well enough to know), but I've seen this used in such a way as to be interpreted as "keep throwing facts at me, as I intend to keep moving the goal posts". A common tactic on forums such as this. BTW, I'm still waiting to see evidence of major Y Chromosome Haplogroups or multiple sub-clades thereof having gotten up and migrated (specifically) c.2193 BC, which is contrary to what is known from the current Y Chromosome Haplogoup Tree - 2010.
