It's unfortunate that we're probably not going to be able to reconcile the science of Velikovskianism to FET.
The events ascribed by I. Velikovsky to have occurred some 3,500 years ago, actually took place a few hundreds of years ago.

There is a question that no one, not even I. Velikovsky, could answer:
One other question, of a like nature. I think it is generally accepted that the Great Pyramid of Gizeh was built before this close approach. The sides of the Great Pyramid are oriented—north, south, east, west—within, as I recall, about three minutes of arc, about the smallest angle one could expect the orientation to be if surveying was done with the naked eye. It seems a rather unusual coincidence that this north, south, east, west orientation could have come out of an Earth that had been thrown into such a chance disorientation by the close approach.The almost perfect north-south orientation means that no tilt or change of poles has occurred since the Great Pyramid was constructed.
In the heliocentrical context, a massive pole shift must have taken place in the recent historical time; however, this fact is disproven by the north-south orientation of the Gizeh pyramid, not to mention its precise calendar of the solstices and of the equinoxes (the Gizeh pyramid was constructed, we are told, well before the time of the pole shift itself).
Moreover, the facts concerning the north-south orientation are even more startling.
"To understand why, we look at Livio Catullo Stecchini, who was a professor of ancient history at Paterson State Teachers College and wrote on the history of science, ancient weights and measures (metrology), and the history of cartography in antiquity.
Professor Stechhini is best known for his numerological theories about the dimensions of the Great Pyramid.
In the 1960’s Professor Stecchini wrote about the apparent inaccuracies detected in the north-south orientation of the Great Pyramid and how these were present with a purpose.
As Stecchini claimed, the alignment axis of the western side of the Great Pyramid was drawn first by its builders, then, the builders outlined the northern side so it could be perfectly perpendicular to the western side. The eastern side, however, was intentionally placed at a larger angle of 3 arcmins, resulting in a larger side.
In other words, the northeast corner should have been 90 ° 03 ’00 “, not 90 °. As for the southern side of the Great Pyramid, it was predicted to be half an arcminute larger than perpendicular, so that the southwest corner measured 90 ° 00 ’30.
However, Stecchini also studied a small line on the floor of the base of the Great Pyramid located near the center of the northern side. Some authors have assumed that this was the original north-south axis of the Great Pyramid.
The data shows that the axis line is located at 115.090 meters in the northwest corner, and 115.161 meters in the northeast corner, so it seems to be a bit off center. This variation was typically rejected as human error.
However, Professor Stecchini concluded that this was not a mistake. Rather, the north-south axis of the Great Pyramid was misaligned on purpose. Therefore, the apex was also misaligned on purpose by about 35.5 millimeters westward."
