Mars Pyramid Claims and the Cydonia Legacy: A Spectrum of Interpretations

To the point

Rumors claim Curiosity found a car-sized pyramid on Mars, sparking theories of ancient intelligent life or a navigation marker, while skeptics cite wind-formed rocks and ambiguous NASA imagery; John Brandenburg's claim of evidence for a nuclear attack on an ancient Martian civilization and traces of a planetary massacre are cited, along with Viking I imagery from 1976 in the Cydonia region showing a face and a pyramid that higher-resolution photos later showed to be natural hills, and multiple interpretations are presented without endorsing any conclusion.
