As both video details, an object which resembles half a head can be seen protruding out of the Martian dirt. The "Face" clearly has humanoid features, two eyes, a nose and mouth.
Remarkable, the face on Mars seems to refer to the Toltec civilization.
The Toltec culture is an archaeological Mesoamerican culture that dominated a state centered in Tula, in the early post-classic period of Mesoamerican chronology (ca 800–1000 CE). The later Aztec culture saw the Toltecs as their intellectual and cultural predecessors.
Just one object on its own is interesting, but with the addition of what appears to be a foundation to an ancient building that is buried in the sand..
and an ancient logogram or pictographic language engraved in a rock, you have compelling evidence that Mars once hosted life, possibly thousands of years ago.
In my opinion these objects are ancient Martian relics, the remains of a statue, the ancient building and logogram are remnants from an ancient civilization (maybe related to the Toltec or Aztec culture) and true to form, NASA is silent.
