Pole Shifting, Magnetic Field Reversal, Library at Alexandria, Time Capules and More

This is a facinating subject. More important it's apparently scientifically valid, at least so I've read. But it's not the same as tectonics, or land moving on tectonic plates, which is also one reason for continents, probably most earthquakes, mountains rising, etc. The popular, and accepted knowledge says that the earth is pretty much now as it's always been. At least for the last few million years. It's taught that at one time long, long ago in a place not that far away, there was but a single continent surrounded by water, that over the millions of years to follow slowly split apart and eventually formed the world as we know it.  The accepted theory is that land moved on tectonic plates over millions of years. But, and it's a BIG but, how do we know that's true, or at the very least the whole truth? 
The last pole reversal was about allegedly 700k years ago. At least that's what a website by Ben Tremblay says, and that it can take 5000 years to take place. Several others say the same thing. Not a serious danger it would seem, unless of course we're in the last couple of the 5000 years, that might be a problem.  As it turns out if you believe the Mayans we are in the last couple of years.
But back to the subject, there is a legend that the Himalayas grew overnight, taking Lhasa in Tibet from being a seaside resort to a town high in the highest mountains.  Accepted theory is that the mountains grew over a million years or so from the collision of the Euroasian and the Indoaustralian plates, slowly pushing the Himalayan mountains in stages ever higher and higher. Which is true? Of course which is easier to believe is much easier to answer.  Mountains growing miles in the air overnight??? Please... But that doesn't mean it couldn't be true, right? 
From what I've read a pole shift or magnrtic field shift, has happened many times. It can cause much damage, and change. Mountains grow out of plains, fertile valley's can become deserts or oceans, islands can rise, or sink, civilizations are destroyed to rise again. Where's the proof? 
What we think we know, or believe to be true today, about the past, even the relatively recent past of 4-5000 years ago, let alone before, is more what we think, or want to believe, than fact.  In fact, we know almost nothing about the past farther back than even the dark ages. As a matter of fact, most people know virtually nothing about the past that's more than a few years. This country the USA, has only been around a little over two hundred years, how much of it's history is already lost?
At one time the Library at Alexandria supposedly held thousands of books, to use the contemporary term, that allegedly went thousands of years back into history. Telling what had existed from then back to the flood, now pretty much accepted to be the end of the ice age about ten thousand or so years ago, or perhaps even what had been happening pre-flood.  Maybe, make that surely, there were things that happened during the 4-5000 years we admit and consider history of civilization, that we know nothing about now, but that had been recorded in a book that was in the Library.  Imagine if you could hold in your hands that, or better, recorded histories going back further, 10-15 25-50 thousand years, or more?  If the Roman Catholic fanatics who burned and destroyed the Library had been stopped, think of what we'd know, it makes me sick to think about it.
As it stands, yes we're rediscovering a lot. But most is unprovable. Yes we think there were magnetic reversals, it looks like there were, maybe in the Library there were first hand accounts, newspapers, drawings, pictures...PROOF!!!  Maybe... Maybe... At this point God only knows. 
There are supposed to be time capsules, chambers placed by one or more antidiluvian civilizations possibly, probably,  more advanced that we are, containing then existing machinery, ie cars, airplanes, and other stuff  I can't imagine, probably also books, information, possibly in electronic formats, video, audio, whatever, located around the world.  Kind of like us burying the Library of Congress, and throwing in tapes & DVDs of movies, old radio shows, and the Smithsonian as well as current and past examples of all autos, planes, boats, trucks, cranes, farming equipment, manufacturing machinery, computers w/peripherals, cameras, furniture, and a lot of other stuff I'm not thinking of. Must be a BIIIIIG cave. Finally,  proof, if we ever find them of course. Is anybody even looking?  One is supposed to be under or near the Sphinx, another in central America or South America, another in the Himalayas near Lhasa, another on Atlantis. In a book called The Cave of the Ancients, Lobsang T. Rampa, aka Cyril Hoskins, wrote about visiting the one in Tibet with a group of Lamas when was growing up in a Lamasary in Lhasa. 
Also, speaking of Atlantis, has anybody ever considered that the Americas could be Atlantis? Depending on how you look at it, they're an island in the mid Atlantic. At least they would be to an average ancient Egyptian or Greek. The only real difference is it's further outside the Pillars of Hercules, much further. Something to think about though...
Anyway, it seems reasonable that these time capsules, or caves of the ancients, would also contain period geological information, on earthquakes, field reversals, mountains growing overnight, comets, end of the world floods, or pending floods/loong rain storms, melting glacers, prehistoric global warming or cooling, together with the more mundane, storms, floods, etc. that would answer a lot of questions. A LOT of questions. Am I the only one curious? I doubt it, but it seems like it. How hard could they be to find?  I ask again, is anybody even looking?
