Your theory here is based on the idea that all surface formation happens the same on every planet. Cite some examples that have proven this.
2: Most Martian water evaporated into space over a long period of time. Obviously, some remains. The Martian gravity well is far shallower than Earth’s.
The scientists who study this can't figure out where it went, if it was there.
3: Martian water originated from the same place that terrestrial water originally came from: accretion of water ice bearing material and hydrated minerals in the solar accretion disc. This is the same place that everything now found on all the planets planets came from: rock, metal, gases, water, hydrocarbons, etc.
Well there ya go. Water came from water. How silly of me. One might have expected some complex sequence of reactions from elements formed after a supernova, but who needs any of that. It's just there.
Where do you think it came from? Do you know of any other source? If so, please share.
I don't know if it was ever there, and the evidence for the claim that an ocean covered a third of the Martian surface is remarkably weak. So what reactions led to the formation of the ice? How did it survive a weak gravity field during the formation of a planet, an event that must generate tremendous heat?
1. Occam’s razor.
2. Send those “scientists” back to school.
3. Duh. How far back do you want to go? The Big Bang? I thought we were discussing planetary origins, not cosmology. How could I be so off-base?
4. An event that must generate tremendous heat. For someone who claims ignorance of planetary processes, you all of a sudden seem to know something. This is quite remarkable.
But, FYI, most recent planetary formation scenarios postulate relatively cold processes. The ball of molten rock scenario has been pretty much debunked.
