If our government has been able to keep it's proof of ETs and their crashe and buried ships and technologies from us, then hiding any evidence of
past civilzations shouldn't be hard or obvious.
Besides, many who might find such evidence may not realize it was that old either and think it was recently buried. Digging up some stainless steel
flatware wouldn't seem like much of a find. Imagine anyone trying to use that as evidence. ........Or is that the running joke?
I had come across an article on The Book of Thoth site on some supposedly related finds such as an iron or steel tea pot buried deeep beneath the
surface thousands of years old and now it's gone from the site. I suppose it wasn't proven as authentic?
I have wondered if anyone has found any real geological evidence of cyclical extinctions such as from the astronomical alignments or planet x etc.
Where's the proof of massive upheavels?
There's most likely some really extensive and highly secret museum and library somewhere with all of these answers for just the elite groups. That
would be an interesting and expensive tour. I wonder if ghosts or remote viewrs aren't allowed either?
