It’s not surprising that the Mars lander found ice on the north pole of Mars. But you have to realize that over 1 billion years ago, Mars was a thriving planet much like earth is today. The ancient alien civilization which once inhabited the planet transported most of its technology and remaining life to the nearest planet, earth.
But what solar disaster caused the water (H2O) on Mars to disappear? Was there some ozone hole that exposed too much solar energy causing the molecules to split into hydrogen and oxygen with eventual dissipation into the black matter of space?
One can only theorize how a once thriving planet was destroyed and left barren. But with ice on Mars, there is hope that some day life may return to that planet.
