Puzzling ancient artifacts

fascinating stuff.

This article reminds me of a quote i recently came across that is quite apropo:

"Like Marks, I am a skeptic, but of a different kind. His skepticism is directed towards anything he regards as "paranormal", taking as normal that which lies within the limits of current scientific understanding. My skepticism is directed towards the assumption that we know enough to proclaim what is possible and what is not." -Rupert Sheldrake rebutting a indivdual trying to debunk his work
