IF
There was once life on Mars ....
Unless Mars is gazillions of years older than earth ... what happened to the good ol' H2O ?
The leftist Martians ruined the planet?
(Martian) global warming?
Evaporated in the warming caused by SUVs
When we finally get that worldwide flood, we’ll only need to send it to Mars. Problem solved on both planets.
what happened to the H2O? Global warming caused by humanoids. After destroying Mars , they built a spaceship and travelled to the next closest planet ... /s
It evaporated and floated into the upper atmosphere, where solar ultraviolet light tended to break up the water vapor molecules into hydrogen and oxygen. The hydrogen was swept into space by solar wind. The oxygen combined with carbon to become Mars' current CO2 atmosphere, and with any exposed iron in the soil to produce rust (which is why Mars looks so red)
If Mars had a thicker atmosphere in the past that got "blown off" by the solar wind, then it's likely that a lot of the water just evaporated. The Martian atmospheric pressure today is far too low for liquid water to stick around. (Water boils at room temperature on earth at around 65,000 feet altitude. The Martian atmospheric pressure is equivalent to that on earth at just over 100,000 feet.)
It Migrated to the Earth like a C-17 Planeload of non English Speaking Afghan Translator’s.
