Another big question about the Antikythera computer: For what the Hell Greeks do need an astrolab, a navigation instrument?! To go from one Greek island to another?, you needen't any instrument for that, even Egypt is so near you do not need that.
Even if you want to use an astrolab it would be useless for the distance involved, so small to see any difference in the measurements between one locations and other.
Or perhaps they used the astrolab to navigate to the Hesperides to bring tomatoes for their salad and tin for their bronze shields.....

About Wegener:
Wegener's theory continue to be ignored. Today theory is the tectonic plate theory that is not Wegener's theory even in both theories continents move. Wegener's theory is rock floating over more dense rock and not a plate of rock that moves.
Beside Australians, who give any importance to Gonfawana today?

Stupidity also evolves!
