@obsidian100 …. i sort of agree. although it seems more likely that, given the relatively short time that the planets have existed relative to the lifespan of our star, planets may begin near their star(s) and slowly rotate farther and farther out as time goes by….so mars is our future and venus is in the state that earth once was. who knows though

@Miles Archer No…it was the Mayans. They built a spaceport at Apocalypse Island

As for the hypothesis that the Sun was much Hotter in the earlier days: the Sun (and all stars) burn hotter and brighter as their lives go on, so the ‘golden zone’ would start closer (Venus) and move outwards from the Sun over time (Mars).

Would other liquids leave the same marks? Makes sense there was water on Mars. Could a planet with different chemistry/temperature/pressure have other flowing liquids (not H2O) that would leave the same kind of track in the rock?

@Bob Mars has icecaps, and yes they are H2O.

Perhaps the solar wind and other things contributed to the erosion, and there wasn’t water at all.

I hypothesize that the sun was much Hotter in the earlier days of the solar system putting the ‘golden zone’ at Mars . It is our turn now with Venus next in line….

Looks like ancient concrete. Are we sure the Romans didn’t make it to Mars?
