Well, none of that applied.
Not sure I understand. None of what applied, and to what?
You could walk on in there and do anything you wanted. I recall a bunch of famous types had their names/initials on the wall at that time.
There are names, initials and inscriptions by a number of famous folks, Byron for one, others wealthy chaps on the 'Grand Tour' in the late 18th and early 19th centuries. The latest I'd heard of were soldiers of WWI.
There was zero discussion of any religious beliefs, even amongst the Egyptians.
If you mean in the 1950s, not really surprising - the religious beliefs in question vanished with the last Pharaoh near two millennia ago.
They just went there to figure out what it was, and apparently they were succesful.
So what was the 'successful' result? A tomb, or a grain store? If the latter, they've fooled the world of archaeology completely for decades - a most unlikely scenario.
You can't mention aliens, or anything like that, without self-proclaimed experts sutting loose with oceans of theory. But... grain silo. Except for that the missing door, the massive salt piles and that chute.... well nm. )
I have read quite a lot on the subject, but I claim no kind of expertise. Doesn't take any kind of expertise to see that building something on the scale of the Great Pyramid, in that incredibly exacting shape, with so little in the way of voids in comparison to the overall size, and purposely for use as a salt/grain store would have to be an act of infinite insanity. It would be the equivalent of building a Buckingham Palace to park your bicycle in, or constructing the Channel Tunnel to run a 'N' gauge model railway from England to France. Four walls and a column-supported roof of a building a tenth the size of the smaller of the three Giza pyramids would be storage space a hundred times and more as capacious as all of the voids in the Great Pyramid combined.
A landing pad for alien vessels is every bit as likely as a warehouse. The pyramids are tombs, or monuments to their gods, or both. A lot of smart people have said so over the years, and I'm inclined to agree. I also believe the Apollo missions actually landed on the moon, and that Area 51 is a place where experimental aircraft are designed, built and tested, thus the many sightings of unusual things in the sky around there. I don't believe Lee Harvey Oswald shot JFK, that 'climate change' is caused by humans, or that 9/11 took place without input from some part of the government resident in Washington DC at the time. I do believe some 'unlikely' things, but the Great Pyramid as condiment and pulse warehouse? Not in this space-time continuum.
