There is something about ancient knowledge that fascinates the crap out of me. The kind of ancient evidence that goes against what we know. We have an established history and millions of books that say 'this is the way it is'. And what interests me is the stuff that gets the panties of scientists and historians in a major knot. There are so many phenomena that are simply ignored because to actually look at it realistically would cause such an enormous shift in our paradigm of the world that nobody wants to even bother.
Anyway, I would go on forever about it, but instead I'll present you with my most recent findings.

This is from a book I'm presently reading.

The Aryabhatiya, an ancient Indian mathematical/astronomical work states:'A year consists of 12 months. A month consists of 30 days'

The ancient Babylonian year consisted of a 12 months and 30 days in a month.

The old Egyptian year consisted of 12 months of 30 days.

Plutarch wrote that ancient Rome (during the time of Romulus) the year was made of twelve 30 day months.

The Mayan year consisted of 360 days.

The Incan year was divided into 12 quilla of 30 days.

The Ancient Chinese Calendar consisted of 12 months each of 30 days.

In all the previous cultures, the addition of 5 extra days to the yearly calendar (and in some cases even the addition of a day every fourth) is indicated to have occurred around the same time.

This is the basis of the theory that at some point in the archaic past the earths orbital position underwent a change. Which leads to many other theories that I won't even get into. Because they involve everything from pole shifting, the changing height of human beings, floods, Atlantis, dual moons and the like.

Okay I've bored you all enough.
