Oh yes, the whole idea that history has been manipulated to cover up anomalies is indeed fascinating.
My Dad is a nuclear test veteran and has researched a lot all round the subject.
One of the interesting things he told me about is areas where sand has been impacted by something causing it to fuse in a particular way that has been seen in test zones. But these other areas are not in test areas. The theory is that it’s a by-product of meteor impact so far.
There are also famous Indian texts that describe what seem to be air battles a few thousand years ago.
There are medieval paintings, of religious type, with dubious things in the sky behind resembling UFOs.
Heck, even the Bible describes people seeing things in the sky that are deemed from “God” …..
There is an awful lot of stuff out there that has been rationalised away….. but we can’t know for sure…..
