Oggy,

You seem to be overlooking the mathematical determinant that agriculture, and thus early neolithic structures, developed in the same temperate zones around the globe! Thus finding similarities in measurements between their megalithic constructs and the equator or the pole is meaningless.

Isn't it far more likely weather and rainfall patterns determined where these first steps to civilization occurred....

Not some mystical knowledge of meters 9,000 years before they were invented...
