Lasting Footsteps: In 1966 or was it 1969, Neil Armstrong was the first human to step foot on the moon. His footprints are still there because there is no wind or rain or other weather that would cause them to erode. Armstrongs footprints and those of other astronauts are likely to remain there forever. Now if Nuclear Winter should happen here on earth and years later some one lands on the moon they might think that aliens or extra - terrrestials from other planets or solar systems were there first and might be wondering just like we are, who could it be.
