Even large stuctures like the pyramids will probably be gone a million years from now. Let alone houses, roads or other similar structures an old
civilisation might have used. And if they developed roughly like we do now, much of their knowledge would be virtual, stored in some kind of world
wide web, like the one we have build and still are building for the last (mere) 50 years. So, the fact that we do not see much of a "footprint" of an
older civilisation does not really surprise me.
And then - there ARE actually a lot of very, very old structures that seem to be build to a similar plan / construction method, all over the world,
which we can't explain either. For example you may want to look into the works of Alexander Koltypin, a Russian scientist, who suggested that older
civilisations left petrified tracks of their vehicles and created huge underground caves.
If older civilisations did what we do today - burn a lot of fossile fuels - you should see evidence of that. And actually - that's exactly what we see
if we study history: there indeed have been periods of rapid temperature rise in the past. So, who knows.
There have been strange, very old objects found that we can't really explain, for example an artifact discovered in London, Texas, USA, in 1934. It is
an hammer - yes, exactly like one you'd expect it to be - embedded in stone. The problem is that the hammer and the surrounding stone are 400 million
years old. The head of the hammer consists of 97 pure iron, 2 percent chlorine, and 1 percent sulfur. Weird OOPART..
But consider another possibility: they never left! They are still here, underground, living in huge caverns, and using cross-breed bio-robots that we
know as "greys" to interact with us...
