3 Mile Doorway To Underground City On Mars Found! Ancient aliens city. UFO UAP Sighting News.

Date of discovery: Oct 11, 2026

Location of discovery: Mars

While using a new Mars map, I came across a huge 3 mile by 1 mile doorway on the bottom of a crater. This looks very old, not thousands but millions of years old and looks long since abandoned. It may have been used for an entrance to an underground city where life could exist more easily than on the hot surface of Mars. Not all life will require oxygen to exist, but comfort is always a high priority for higher intelligent lifeforms.
