It is believed by members of the UFOlogical community, that
the evidence found on photos taken from the surface of mars, is that there was once an advanced society living on the planet,
who built giant structures, and some cataclysmic event transpired, which caused them to leave.
Not only is it believed that they created these monuments
on mars, but it is believed that they created similar structures on earth so that when we developed the technology to view
and visit other planets, we would find the correlations between our races.
After closer examination of nearby structures that appear
to be pyramids, one resembles a large city.
