Question

Neil Armstrong, the first human being to step on the moon, left a foot print that is essentially unchanged nearly 50 years later. How is it possible for this, and all the other footprints, tracks and markings, left on the lunar surface to remain unchanged for so long?

Answer 1

Since the boot-print was left there nearly 50 years ago, there has been very little wind and very little rain in that area, and plus, there have been very few people or other animals walking around in that spot to disturb it.
