Curiosity Rover landed in Gale Crater which is three miles deep and one hundred mi across, which means the impact that formed the crater displaced some 7,500 cubic miles of volcanic ash, to reveal an ancient surface that is in large part intact!
The ash blanket that covers much of Mars' surface came from successive eruptions of volcanoes on the Tharsis Shield, which are said to have occurred between "3.7 billion and 500 million yrs ago."
The classical civilization that produced the statues and built the stone platforms predated the Tharsis eruptions, which enlarges the evolutionary time frame out of sight as well it adds the dimension of space travel.
Data returned by the Soviet Venera program that went from 1961 to 1984, that proves humans inhabited planet Venus has similarly been kept under wraps.
