There is another demonstration of man or pre-man. Maps etched in metal
have been found in Russia which are millions of years old. Sorry, I
don't recall any details, but several months ago I saw some reporting on
it.

I do not think that any of this, if true, will deal much of a blow to
the THEORY of evolution, but it may change our views of some aspects of
it. Man may have come and gone many times over eons.
