The dropa discs also seem important to me.
And I know some people are now going to say it's fake because the person of a book has admitted he made it himself etc.
But if that would be a fact this disc wouldn't be in the French museum anymore, it really wouldn't.
And don't say that those scientists and museums don't know what the age of the Dropastones have, because I rather do not believe sites which claim
it has been confessed etc... because that isn't true
It isn't in a museum and checked for age because it a a hoax which even has been admitted
