How did an ancient primitive tribe know such detailed information about a star that was measured only now?

No. There is no proof they knew anything before anyone else.

Aliens visited Earth long ago and left knowledge everywhere. Check out Von Daniken... his books. You can also check Zacharia Sitchin.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
