Eddie,

The professionals may forget what the rest of us--even today--can't avoid noticing: our changing orientation toward objects in the sky. It happens every day with the sun--and the moon by night. Then we notice the night sky changing: and we're hooked!

Looking to Nabta Playa--or Stonehenge--or whatever site we discover and explore--it becomes obvious that we weren't the first. Other peoples, going back in time, made and shared similar discoveries--and made those discoveries part of their lives.

As we begin to get more hints that their knowledge was more "modern" than we attributed to them, it makes us rethink how cognitively primitive man was before presumed "civilization" educated him. Having grown up in backwoods America, I probably shared way more in common with those who visited Gobekli Tepe than most would suppose: seasonal cycles, living off the land, constantly looking up at the night time sky.

Seeing us as continuations of them, thinking in much the same way, is no stretch for me.
