*** Oh boy, Palsing, you're a real crackerjack when it comes to
Astronomy. The Oort Cloud is populated almost entirely by icy objects.
Every now and then one gets bumped from it orbit and does indeed become
a comet and the ice is gradually turned into vapor as it approaches the
Sun.Â* BTW, that's how Mercury, Venus and Mars got their water. Mercury's
was vaporized by its proximity to old Sol, Venus is shrouded partially
by its steam and Mars lost its water due to some cataclysmic event that
exposed its surface to the Sun and its surface water evaporated.
If you have any more questions, just ask.


You are saying nosense

Mars did not lose its water due to some cataclysmic event,

Three main reasons explain the loss of water from Mars

- The Late Heavy Bombardment approximately 4.1 to 3.8 billion years ago

- The disappearance of magnetic field 3.7 to 3.2 billion years ago

- And in addition, the loss of water is progressive even now

Before 4.1 billions years ago, the Mars atmospher had the same pressure
and temperatur as the currently Earth, with rains, rivers and oceans
