So, a group of archeologists from the year 4978 have uncovered something strange. They’ve been searching for the missing link between them and their primordial ancestors, and they seem to have found something interesting. Their was a a large stone, sticking up from the ground. On it were some unintelligible squiggles that read “Here lies Robert Paul Smith 1983-2057” They started digging, and they started finding remains, that looked nearly identical to modern human skeletons.
They don’t know it yet, but these future archeologists have just uncovered an ancient human burial ground. It is a modern cemetery to us, but they don’t know that. They can’t read any headstone markings, as they speak a different language. So my question is:
In a modern cemetery, what evidence could you find that the skeletons buried in the ground were intelligent?
In a cemetery, what evidence could you find that an intelligent, technologically advanced species existed?
