The mechanism in the case of a stoppage in rotation and a reversal of rotation, Penny, would most likely be an "off-Earth" mechanism...that is, very large gravitational factors emanating from other large objects in space....conjunction of various gravitational forces at cyclical intervals in the Solar System...or beyond the Solar System, in the Milky Way Galaxy. I've read some interesting theories about that. If so, we are not in a position to examine the evidence, because we don't have access to it, aside from our usual observations of the sky through telescopes and satellites.

If it's something that only happens at very widely separated intervals, there may BE no visible evidence suggesting it at this time.

It is likely that some of our planets were once not yet established in their present predictable orbits, but were "wanderers". Velikovsky wrote some very interesting stuff about that in "Worlds In Collision". He suggested that Venus had once made a fairly close pass to Earth, causing much devastation here, before it (Venus) settled into its present orbit.

I imagine an event like that could have significant effects on this planet's rotation...and other such events may have occurred at various times with bodies other than Venus.

We have no way of securing evidence about it, do we?

As for evidence of the Great Flood, there may be more of that than you think, but our concept of it may be quite primitive. It may not have happened in a period of days...or everywhere at the same time...but it may have been an extended period of unusually heavy rainfall and much flooding of different large areas over hundreds or thousands of years...due to various changes in the Earth's atmosphere, and changes in climate patterns. The flood myths have probably greatly simplified the actual event by localizing it and putting it in simple, symbolic metaphor rather than a literal description of what occurred.

Are you aware that the soft sandstone sides of the Sphinx show definite evidence of extensive water erosion caused over a lengthy period of time by either torrential rains or surface flooding or both? North Africa was fertile than, and there was a lot of rain falling there.

The Sphinx is almost certainly tremendously older than conventional Egyptologists are willing to admit. It's probably at least 20,000 years old. It predates the known Egyptian civilization, and was probably built by a previous civilization that we know nothing about. The Egyptians, in effect, adopted it and probably resculptured its head into a slightly smaller human head (of a Pharaoh) at some point. The original head may well have been that of a lion. It looked directly toward the sunrise.

Like most people in any historical period, almost all of us think that our present scientific and authoritative community have "the answers". As in all previous periods, I think they are in fact dealing to a great extent with their own mythological notions about the past, and their own gross misinterpretations of it which they simply take for granted and wouldn't dream of questioning.

They aren't, in my opinion, nearly as well-informed as they think they are. Nor are any of us. Me included.

There's a simply TREMENDOUS amount of stuff about the past that we are all either starkly ignorant of...or quite mistaken about. But most people don't see it that way. They think they already know the score! ;-) And they think Big Brother has told them the truth all their lives, but Big Brother is not playing with a full deck of cards, and never has been, and probably never will. Big Brother is just a consortium of other impressionable people like ourselves! ;-)

I apply a healthy dose of skepticism to the most common assumptions about most things, and I consider all the alternatives. I admit that I have no way of knowing for sure about any of them, but I keep looking into it. Why? Because I'm curious, and I'd like to know. ;-)
