Seb146: The one thing I do not understand about Stonehenge and the pyramids in Central America is: If they were build using presice calculations of the sun and stars at the time of construction, then, since the earth 'wobbles' and stars fade out and change position over time, how can these things still be precise today after all these thousands of years? When the sun at equinox hits the stairs of one pyramid in Mexico, the shadow forms the body of a serpant. The equinox also can be calculated with Stonehenge.
The earth´s rotational axis
has not changed (or not much), so everything that only depends on the apparent position of the sun
still "works"; Star
positions, however, are no longer matched. The egyptian pyramids, for instance, probably had some of their parameters aligned to certain stars. But that is no longer true today.
EGGD: If it was built by Germans, you'd probably be able to drive it with tiptronic transmission, fit 4 kids in the back and still have space for 3 suitcases in the back.
Who knows... Has anybody located the fuel tank
