Mars elevation map, 2002 MOLA
The paper in Nature Communications sets out some of the possibilities for a Martian ocean in motion: fluctuating shorelines, tsunami deposits, sedimentary layers and deltas. Luo does not speak of any floods. It’s amusing, however, to see planetary scientists routinely refer to a “Noachian epoch” on Mars.

Mars has no magnetic field. Solar wind blew away the atmosphere and with it the water.
“Mars lacks the atmosphere that could keep it liquid. It’s also too cold for liquid water”
Mars had a much thicker atmosphere and therefore was warmer. Mars lacks a magnetic field therefore the solar wind eventually blew the atmosphere into space.
It would be fascinating to get some cores drilled to see whats down a few hundred feet under the ground there.
It is too disgraceful and ruinous, though, and greatly to be avoided, that he [the non-Christian] should hear a Christian speaking so idiotically on these matters, and as if in accord with Christian writings, that he might say that he could scarcely keep from laughing when he saw how totally in error they are.
-Augustine
The belief is that Mars was once like earth, but being smaller its core cooled and solidified faster, shutting off its magnetic field. With no magnetic field to protect against the solar wind, its atmosphere leaked away into space. Liquid water cannot exist without air pressure, so the oceans either evaporated or froze. It is likely that there are still oceans worth of water ice in the regolith, but it’s too cold and the air pressure is too low for liquid water.
Great post. Atheists have more faith in so called science than truth. Did you see Is Genesis History.
“There is no ground truth to assess the real accuracy of our estimation,” he says. In planetary science, that’s OK these days. If your model requires it, that’s enough reason to believe in it, even if you can’t imagine how water could exist on Mars at all. Someone’s rule of speculating is that if you’re going to tell a whopper, you might as well tell a really big one:”
