With our society and technologies, most of our materials would rust away or decompose... our current junk yards would be what, iron or tin mines in
the future. Glass shards, broken over time, could be grouped in a catagory similiar to crystal formations, or 'naturally occuring due to pressure
and heat'. Plastic is something different.
I can not think of a way to explain away plastic deposits... maybe a form of petroleum not yet liquified.
Concrete and cement... ha! The things we have constructed today is nothing like that used hundreds of years ago. Look at your driveway, or your
roads, and compare them to the Colluseum, and you'll understand what I mean. Those will crack and break apart, erode, and become like those rock
formations/foundations found by the Martian Rovers.
I'd say go to my other thread (I think it was called 'Why are we the only civilization') for more information... Gazrok gave many good valid points
for us being the only ones due to lack of evidence/garbage, and many others gave good points for there being proof (odd findings such as screws
embedded in coal, metal workings encased in stone, etcetera); that is, I would tell you to go there, but this new 'search' thingy is so fickle...
