Moon... our "postcard to eternity"

Just read this comment online - wow, how true.

Dinosaurs ruled the earth for 160 million years and died out 60 million years ago. Our species has been here for 100 thousand years or so and will probably be extinct within a million years from now. We are to date, evolution's only experiment with technological intelligence that we know of. Maybe in another 60 million years another technologically intelligent species will evolve. If so they will find little or no evidence of our existence on Earth over such a long span of time. Our cities, metals, alloys, nukes - everything - will be just another thin strata in the rock. Nothing we achieve on Earth has the power to endure over geological time. A few fossils may remain and maybe some anomalous objects which may be interpreted as artifacts. But nothing of us and our achievements as a species will remain. Apart from on the Moon, where, barring direct meteor hits, nothing will have disturbed the remains of the Apollo missions since they landed there. There is no erosion on the Moon. The Lunar Rovers, the experiments, the launcher for the Lunar Lander, all of it will sit there in it's brand new state, as if just vacated by the departing astronauts. Would not future intelligent species not wonder at our achievements when presented with this evidence? Apollo is our postcard to eternity on which we have written, We Were Here.
