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!

Curiosity Sol 1035 returned July 5, 2015 - Has cliplock iron roofing which was first produced in Australia in 1962, protruding from under about a meter of mudstone, itself covered by no less than three miles of volcanic ash .. think about how it got there & conclude the only viable explanation is extra planetary time travel.

The stone axes that litter Mars' surface are identical to prehistoric stone implements uncovered on Earth, while data returned by the Soviet Venera Program similarly proves there were humans on planet Venus.
As well a similar stone axe [and a boat] was located in a shot returned from Venus by the Russian Venera Program that went from 1961 until 1984 .. we say the same tribe of space faring time travelers seeded all three planets with the same stone weaponry, in much the same way guns are being poured into black murder hotspots in Baltimore, Detroit & Chicago and for the same reasons ergo to cause trouble.

On Sol 115 of the Opportunity Rover Mission May 24, 2004, the the vehicle ran over an obstruction that looks for all the world like a railway sleeper cut from West Australian hardwood, which we say likewise proves time travel unless someone has another explanation re how it got there .. that the movers & shakers at NASA never took a closer look makes a mockery of the entire mission.
