tweva, I’m a bit confused by this. Where do those two essays come from?
Coming to your “What if this is true?” question, no I haven’t given much thought to catastrophic earth changes that occur on a timescale that we’d notice. I don’t know if you ever heard of Immanuel Velikovsky who wrote a series of books starting in the 1950’s. His most popular ones were his 1st three: “World’s in Collision”, Ages in Chaos” and “Earth in Upheaval”. He details major earth changes that historic peoples did experience, which if they occurred today would be beyond comprehension given our populations and inter-dependencies.
