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

Very Highly Esteemed colleague,
as Einstein said: "everything is relative"...
It depends on what we choose as our point of observation... :p
A glass includes water... this is evident from the preposition "in," i.e., water (or alcohol) is in the glass, therefore it doesn't become a layer... because the water and the glass become inseparable...
Therefore, the statement "there is water on Mars" becomes true!

With very deep respect for the Very Highly Esteemed colleague!

Very Highly Esteemed colleague, from your statement

water and glass become inseparable

, we can conclude that:
1. water/alcohol has attached itself to the glass, or the glass to the water/alcohol.
2. the molecules of the glass walls have mixed with the molecules of the water/alcohol.
3. the temperature of the water/alcohol has dropped below the crystallization temperature of the liquid, and it has simply frozen to the layer between Mars and itself.
4. ... and so on.

However, it is very easily proven that this is impossible:
1. water/alcohol does not have such hooks, and the glass does not have a loop-like fabric like on your sneakers or backpack (to prove this, try to examine them in the picture).
2. if this were to happen, we would be able to see droplets of water/alcohol on the outside of the glass in the form of dew or sweat.
3. in this situation, water/alcohol cannot maintain the same purity and transparency, and frost should have formed on the outside. And in general, this concerns the question of whether there is snow on Mars. + water and alcohol have different freezing temperatures, i.e., to prove this, we would need 2 pictures, and that is very expensive (you have no idea how much it costs to take a picture from space, from a vacuum, with a Kodak-type camera).
4... As you understand, all subsequent statements are also easily refuted.

From all of the above, only one conclusion can be drawn: water/alcohol and the glass are separate from each other, and therefore the glass is a layer between "Mars as a whole" and the water/alcohol/Kremlin vodka.

However, during a smoke break, a key point was discovered, i.e., the main mistake of our Very Very Highly Esteemed colleague Ambersoler when submitting this topic to the forum with such a statement.
We have a literary translation from a certain dialect of English (African-American or Afro-English?). For these people from a distant overseas country, there is no difference between "ON" and "ABOVE," so it is possible that this picture is being interpreted as proof.
But in our language? Colleague, try to send someone "ABOVE..." and what will happen? It will turn out to be something insignificant. But if you send someone "ON..." or you are sent "ON..." then it's a completely different matter!
Colleague?

P.S. Experiments involving the use of the preposition "ON..." in relation to me are not recommended by the Ministry of Culture of the Russian Federation.
