Can anyone add more to this list or provide evidenced opinions of why the ones I've listed aren't valid.
Sorry to bring an old thread back to life, but has anyone considered this question...
Advanced by what standard?
Advanced and technological doesn't inherently mean a consumerist based society creating technological products for the masses thus necessitating the
need to destroy vast stretches of land to produce these products for consumption and eventual waste leaving behind evidence of such activity.
Perhaps they were advanced by means of being more connected to and knowledgeable of the Earth. Using natural resources in a sustainable fashion
wouldn't leave much evidence behind. Thing's such as flight would still be possible, electricity is a possible maybe. I could personally think of
many thing's we do today that could (and in my opinion SHOULD) be done differently that wouldn't leave much trace of any real advanced intelligence
behind it 50,000 or even a hundred thousand years from now.
I'm just saying, advanced doesn't inherently mean the utter rape and destruction of an entire planet for the sole purpose of greed and consumerism,
so perhaps we shouldn't be looking for such a type of "advanced" civilization.
