I never believed much in Atlantis --- not like I did in Nessie. But I just watched a fascinating show on PBS that, whether Atlantis is ever found or not, shows that disappeared civilizations on a massive scale is hardly unusual.
I had never heard, for instance, of South America posed as a possible site for Atlantis before, and the evidence is hardly strong, but did you know that the ancient Egyptians put tobacco and coca leaves in their mummies now and then? Ends up the oceans were much more porous in ancient times than we realized.
And an awful lot of South America's been destroyed from time to time. And massive civilizations existed in more places than we knew even ten years ago.
In many ways, I felt like I was watching a documentary on Book of Mormon archaeology. (Put that in your Egyptian pipe and smoke it.)
But mostly, it made me realize that we really know so little about anything and as soon as people start talking confidentally about us knowing anything (but especially the future or the past), it's time to nod our heads and walk away.
We'll know more tomorrow than we know now.
And we better not be too secure in our wrong opinions.
