Well, I believe that most modern buildings will be collapsed after 250yrs, and completely gone in a few thousand. Quite a lot of places would get buried, and when left unchecked, vegetation is very destructive. Apparently the pyramids and other such giant structures would outlast most other buildings, but eventually they too will get eroded or whatever... after all, they've only been around for about 7,00yrs (?) so far, say another 100k and I imagine they would look just like lumps of rock, a few more k's and not even that... quite scary really to think how quickly traces of modern civilization will disappear. (although our bits and pieces on the moon will be around for aaaages).

So how did humans survive with dinosaurs.
It makes you wonder if the meteorite hadn't struck Earth and wiped them out, would lizards be the dominant species ?

They didn't. Dinosaurs were extinct long before humans existed.
Off the top of my head, I think there's a 60 million year gap between the last dinosaurs and the first humans.
It begs the question then, what fossils did the dinosaurs dig up?
Tory politicians I think.
I watched a TV program about what would happen if all the humans suddenly died, and all trace that we ever had more than flint tool would disappear remarkably quickly... Dinosaurs could well have had cars and computers, but there wouldn't be any evidence of it... Evidence of things that happened longer ago than yesterday disappears pretty fast!

He is right, weathering and plant growth tear even the strongest of buildings to pieces within a few hundreds of years, the only reason they stay ok is because they're maintained.
Before you say what about the pyramids etc, that is because they are in a hot, dry low salt area, and as such moss and plants haven't taken hold, however if we weren't maintaining them now, they wouldn't last much longer, i,e the nose falling of recently.
if you think about it, how weird is it that they were on this earth way before and way longer than us and if we had never discovered and fossils or preserved bodies, we wouldn't even have known about it.

The trackways show that large tetrapods, up to three metres in length, inhabited the marine intertidal zone during the early Middle Devonian some 395 million years ago.
"This means not that not only tetrapods but also elpistostegids originated much earlier than we thought, because the position of elpistostegids as evolutionary precursors of tetrapods is not in doubt, and so they must have existed at least as long," says Per Ahlberg.
The elpistostegids, it seems, were not at all a short-lived transitional stage but must have existed alongside their descendants the tetrapods for at least 10 million years. The environment is also a major surprise: almost all previous scenarios for the origin of tetrapods have placed this event in a freshwater setting and have associated it with the development of land vegetation and a terrestrial ecosystem.
"Instead, our distant ancestors may first have left the water in order to feed on stranded marine life left behind by the receding tide," says Per Ahlberg.
