A valid point, theminstrels. To be sure, the people of the past possessed the exact same brains as we do because, like us, they were Homo sapiens sapiens. The same cognitive abilities and potential were there.
It drives me a little batty when people suggest ancient civilizations were much more advanced than we modern folks are. Such a notion is absolutely ludicrous, of course. Even some of our most basic technologies--newspapers, radios, toasters, microwaves--represent a level of science far, far beyond what ancient peoples could only imagine. To suggest that we could not possibly build something ourselves like the Great Pyramid is just silly, although not quite as inane as suggesting aliens did it.
Still, it is always fair to acknowledge that the level of technological sophistication at which we stand today could not have been obtained had it not been for advances going all the way back to ancient peoples.
LOL It surprises me that this old thread still pops up now and then. Most of the discussions I start just don't last that long.
