Truth-seekers say the still images from a NASA rover on the Red Planet clearly show inhabitants of some sort left their mark on Mars.
YouTube user Paranormal Crucible wrote alongside footage of the stills: “Interesting artefact that for me confirms yet again that an ancient civilisation did exist on Mars.
“Not many natural rocks have hair, eyes, a defined nose and lips.”
Another commented: “Seems like Mars is forever revealing its secrets.”
Faces being spotted in NASA images from the Red Planet are not actually that rare.
Last week, conspiracists went nuts over a picture that appeared to show a googly-eyed alien face on the planet”s surface.
