In both images, an object that looks like a half head protrudes from the Martian soil. The “face” has two eyes, a nose, and a mouth, and is clearly humanoid in shape.
Surprisingly, the Toltec culture seems to be represented by the face of Mars.
The Toltec culture is a Mesoamerican archaeological culture that ruled a state centered on Tula during the early Postclassic era of Mesoamerican chronology (ca 800–1000 CE). Later Aztec culture looked to the Toltecs as intellectual and spiritual ancestors.
When you combine that with what appears to be the base of an ancient building hidden in the sand and an ancient logogram or pictographic language embedded in rock, you have compelling evidence that Mars once harbored life, most likely thousands of years ago.
The remains of a statue, the ancient structure and the logogram, in my opinion, are relics of an ancient civilization (possibly related to the Toltec or Aztec culture), and NASA has remained silent, as usual.
