I have been thinking a lot about how much ancient cultures knew about, mapped and catalouged the "heavens" or the sun moon and stars/constellations (thousands and thousands of years before operation paperclip and NASA)
In particular its amazing that they catalogued the Precession of the Equinoxes in the Zodiac which is an unbelievable phenomena that lasts something like 25,000 years then repeats its cycle. Every 2100 years or so, the sun rises in front of one of the 12 particular constellations of the Zodiac. The precession of the equinoxes can only be explained by ONE THING... and that is Axial Tilt of a sphere or globe. The fact that they knew it repeats every 25,000 years means to me that ancient cultures have known about this information and passed it own for AT LEAST one or two of the 25,000 year periods (maybe more)
