There’s a non zero chance that Mars is a remnant of the planetary impact that occured to the Earth ~ 3.5 BYA. The issue is that’s a really loose hypothesis, but the speculation is that Theia - which impacted Gaia (old Earth) was an ice planet / water world, which gave us most of our oceans.
Evidence of water evaporation on Mars therefore makes sense, as a catastrophic effect (such as planetary impact) would indeed cause the atmosphere to boil off, leaving behind these dry lakes and riverbeds.
I personally haven’t spent enough time on Mars to make a substantial conclusion, there wasn’t enough time to do any science between the sheer insanity of basic survival on a planet that seems uniquely designed to kill you and crush your spirit before doing so.
I totally approve of your analysis however, and it’s proof why geologists deserve a seat on the interstellar jumpships :3
Furries are simultaneously morons and rocket scientists/brain surgeons or whatever.

Be nice to them, you never know when your lifesaving medication was made by a furry. :)
