Previous Technological Civilizations? Creative Criminal Activity

Wednesday April 2, 2014  "Creative Criminal Activity Contest," said a poster on the U of Minnesota campus.

It was a contest for creative ways of reducing crime on campus.  Not for creative ways of being criminal.

***Found a backpack I liked better than any I owned at Steeple People Thrift Store.  Thought about the reasons why I shouldn't buy it.  Bought it.

Thursday April 3, 2014  Spiderweb, in a cup I'd used a few hours earlier.  A sign of Spring.

On the other hand, a winter storm warning.

"I've often wondered whether it's possible that there was another technological species on our planet in the distant past.  What signs should we look for?

"I'm skeptical that one can be ruled out more than one billion years ago, however.  There just isn't much left from those times.

"On the other hand, there is the nuclear waste found in Africa dated to one and a half billion years ago, usually attributed to a natural nuclear reactor.  Well, maybe."

My guess:  If there was a previous technological civilization, any relics it left would be interpreted as having other causes.
