Sinis,
No natural events do not come into the picture when the ancients describe the "gods". The sumerians, primarily, are very detailed in mans "creation" and WHY the "gods", who the describe as nothing more than aliens, made man.
Of course they do. What did the ancients make of an eclipse? Earthquakes. St Elmos Fire? Lightning? Thunder? Floods? Northern Lights? Whirlpools? Strong Winds? All these natural events were interpreted as the manifestation of some God or the other.
Natural occurences do not support HOW men moved and lifted the trilithon in the Temple of Jupitor, nor does it support how men made structures that rival some of the worlds most advanced construction equipment, etc. No, what we "moderners" tend to do is equate such feats with the catch all phrase - "lost knowledge". Yea, right...
Yes, they do. You need to do a little more research on the matter. A scientific methodology applied to these previously 'inconceivable' matters have all yielded techniques that allow for such feats of construction. I know it is much more exciting to imagine that aliens designed the buidlings in Rome, or that levitation was used to build the Pyramids, but it is pure Von Daniken poppycock. All of this has been debunked.
The Roman aqeduct, which has a fall on 1/4" over many miles, is a much greater feat of construction than lifting heavy stones Sinis. But construction plans and methods have been uncovered that showed how they were built.
