A photograph of water on Mars has been posted on the NASA website!

Brilliant!!!
You know, colleague, I can't agree with you again.
Mars, on the contrary, has incredible gravitational force, because alcohol and the glass are separable, and your attempt to flip the photo of the glass did not result in the alcohol spilling.

If "Mars" had such incredible gravitational force at that size, as you claim, then it would have to have a monstrous mass... based on the formula of mutual attraction (I didn't invent the formula, Newton did)...
and having such a huge mass and such small dimensions, it would have long ago ceased to be Mars and become a "black hole" - but that is not true! because the photo shows "Mars"!
