Thanks Mackenzie. Guess we were both having a bad day? Your comments really didnt bother me much, actually, and the written word sometimes can give the wrong impression, something we can all be wary of.
There was this show a while back on History Channel about what happens if humans vanish overnight. Cars, books, buildings, bridges, all of it will pretty much vanish, and there will be little trace of us within a thousand years.
In a way, it is too bad more inorganic stuff was used by the ancients, so we would have a better archeology record of our ancestors.
