no one knows, we just discovered.
Mars lost its water (or it all froze) fairly recently . . . about 1 million years ago.
it did bilions of years ago but its all dried up now
Mars is believed to have formed about 4.6 billion years ago, around the same time as the rest of the solar system. It was formed from the same cloud of gas and dust that gave rise to the Sun and the other planets.
The magnetic field on Mars is only residual, it collapsed many eons ago.
No, water did not come from the asteroids a billion of years ago.
about 4.5 billions years ago.
mars has had frozen water since is was cretated buy God, about 4000 years ago.

No, but there is fossil evidence to suggest that there was very simple forms of life (bacteria) on Mars many years ago when the planet still had an atmosphere and unfrozen water.
Earth, but there could have been water in Mars years ago.
11,600 years ago.
no, but we think it might have done many millions of years ago
the are long, narrow channels that were most likely carved out of water millions of years ago. hope this helps :)
Mars' atmospheric presure is 1/100th of earths. Beacause of this extremely low pressure, water can't exist on Mars in its liquid form because it boils instantly
