trading, my paternal grandmother studied history and she was totally into all the ancient cultures (Egyptians, Maya, Inca...you name it). What she always found strange, was that the first pyramid was spot on, but the younger ones... it seemed that they forgot how to build them. Therefore she already figured before the tomb of King Tut was found in 1926 (she was born in 1894 btw) that the original structures may be much, much older. We discussed all of that when I was much, much younger :-) and we both sort of reached the conclusion, that there must have been highly developed societies, but the went into decline. Perhaps because of a natural disaster or some high-tech war. The most logical thing to do in this event, would be to gather the cream of the crop of engineers, architects, etc, and build something from extremely solid rock to leave the message "We were here" and then write in pictures, rather than using letters.
I have watched a very interesting documentary on Youtube about a year ago called "The World without Humans" and according to that, with our now modern structures, cars and stuff... assuming that all humans would simply just disappear right now, a visitor to planet Earth arriving about 15000 years after this event, would never know that we (as in humans today) have ever existed (as everything would have completely disintegrated) but they might still see the pyramids and all the other huge stone structures.
I highly recommend that documentary to you.
