Do the points of the crescent form a line which is perpendicular to the line which points toward Mecca?
Whatever a crescent might have meant nearly 10,000 years ago is unknown.
One of the more interesting developments going on is our ability to use radar to look underground ~ it tells us about the buildings, monuments, campfire grounds, and hunting camps of the ancients.
There are suddenly literally thousands more interesting archaeological sites than we had before ~
The internet also enables us to use simple tools ~ e.g. satellite pictures ~ to examine town layouts all over North America to find the core of old French cities, old Spanish forts, and in some instances, signs of the more highly advanced Indian tribes in North America proper. An amateur can do more sound research of that kind on his own in a couple of evenings than a graduate archaeologist could have done in a lifetime. Doesn't mean amateurs are doing all the work, but they can easily find places to look.
I canna stennis anymore.
