Hello there TheColdDragon
An interesting speculation, however if they had nano technology that could eat everythng then the world would be gone! Obviously that didn't
happen.
Sure a super technology might be able to complete erase a civilization but that in itself would leave traces, destroying stuff leaves traces in the
soil - now if this technology was so powerful that could eliminate every trace of artificality and nature then yes we couldn't detect it - and if
the technology that did it was also completely erase -then yes we wouldn't detect it.
Hey there Apacheman
In many of the example you cite we DO or have found those civilizations so in that sense your arguement is moot. However I believe your point was that
as we learn more we will find more. A meteor wiping out shore based civilizations? There was an event that affected NA but it hasn't been shown to
have affected anyother civilizations (we haven't found any) saying something is proven when its a new theory is always risky.
Look at how many fruits and veggies originated in either North or South America that have become staple crops worldwide: potatoes, tomatoes, maize,
etc. What is particularly notable is the biodiversity of those crops, most probably the result of advanced agricultural research, which itself was
necessary because of the impact consequences.
We know in many cases how these crops originated and can still find traces of the original species. If they were, bio-engineered, then the
'advanced' civilization was a bit dense. You might want to look at how we think maize evolved from Teosinte.
were far more advanced politically, socially, and agriculturally than they the Europeans
Very debateable. I love the Maya but they were not socially more advanced, their culture was an elite based system of city states that constantly war
with one another, there agricultuaral system collapsed. The Aztecs killed hundreds of thousands for religious reasons. The Incan were imperialistic.
etc. I think we could points in some areas to the natives but nothing that would indicate a previous culture, they appear to be all local cultural
evolutions and emergences.
You might want to start a separate thread on that idea however.
