Lots of mysteries and lots of lost information.
They found isotopes on the moon that only come from nuclear explosions, as far as we know.
A lot of things can only be seen from the sky like the Nazca lines.
When nations were invaded by others, usually their written records were destroyed, or if something of interest hoarded up by a select group of people?
I've always found it strange that if a person lives to be 100, then it's only 50 or so people ago to pyramid construction times... yet we know nothing about what went on in those days outside of hieroglyphs that mostly express daily life.
Pyramids were being built around the earth about the same time, so people were connected somehow.
The Tower of Babel
11 Now the whole world had one language and a common speech. 2 As people moved eastward,[
a] they found a plain in Shinar[
b] and settled there.
3 They said to each other, “Come, let’s make bricks and bake them thoroughly.” They used brick instead of stone, and tar for mortar. 4 Then they said, “Come, let us build ourselves a city, with a tower that reaches to the heavens, so that we may make a name for ourselves; otherwise we will be scattered over the face of the whole earth.”
5 But the Lord came down to see the city and the tower the people were building. 6 The Lord said, “If as one people speaking the same language they have begun to do this, then nothing they plan to do will be impossible for them. 7 Come, let us go down and confuse their language so they will not understand each other.”
8 So the Lord scattered them from there over all the earth, and they stopped building the city. 9 That is why it was called Babel[
c]—because there the Lord confused the language of the whole world. From there the Lord scattered them over the face of the whole earth.
