The mountains around here are very ancient ~ among the oldest ~ except, of course, for the even older mountain chain buried under thousands of feet of solid rock in Indiana!
Those suckers are OLD.
Heh, heh. That's kinda my point. How can we be sure the age of other mountain ranges are accurate?
I place no faith in scientists when it comes to stuff like the age of the earth and evolution and the origin of life.
When it comes to those things, they don't know jack. They just make stuff up as they go along.
