The Story According to NASA

Lunar Orbiter 5, Frame 168-H2

Down slope boulder trail and boulder on the Moon

Lunar Orbiter 5 image of a boulder (just right of center)
which has rolled and slid down a slope and left a trail on the Moon's
surface. This is within the crater Vitello, and demonstrates the small
role that such processes, called gravity wasting, have on the lunar
surface. The main source of surface modification on the Moon is
meteorite and micro meteorite bombardment. North is up.

1) Looking at the “track” it left behind, the object is the same width as the track.
Rolling rocks leave imprints that are narrower than their width. If it was something
rolling, it must have had a cylindrical shape rather than a ball.

2) If you look at the “track”, the object went straight through a depressed part of
the terrain without altering course or simply getting stuck in the depression.
Then it went uphill out of the depression and continued in a smooth, undisrupted
path.

3) How does a rolling rock leave such a complex pattern seen in its “track”?
If it was a rock that's round enough to roll that distance, then what kind of
“tread pattern” could a rock possibly have to leave such a pronounced “track”
that is the same width as the rock itself?

They knew about the alien activity on the moon way back then .
