ok, not sure why you feel this is relevant to water existing prior to plants.
Mars and water?
1) Mar's atmosphere is mainly CO2 (95.32%).
ok, still not sure why this you think this matters.
2) The poles on Mars gets so cold this CO2 freezes and falls like snow making it look like polar ice caps exist,
Did you read the article you linked, because it states quite plainly that water exists on mars. Nobody is saying mars currently has oceans of liquid water on the surface, that would be absurd. Mars is known to have water vapor and water ice and has the potential for liquid water underground. Water ice and vapor are still chemically H2O which is what you said required plants to produce via oxygen production. Since there are no plants on mars, the moon, or interstellar space, and H2O exists in those places, it's reasonable to conclude that plants are not required to produce water.
3) The atmosphere barometric pressure is 1/4 - 1/8 that of earth. Which means that any water there would boil at around 50 degrees. Which means all evidence of of oceans etc.... Would be in the atmosphere in gaseous state. But that is not what we find. There being mainly CO2 means there was no water.
These clouds of water-ice were photographed by the Opportunity rover in 2004. NASA scientists working on the Phoenix Mars mission confirmed on July 31, 2008 that they had indeed found subsurface water ice at Mars' northern polar region
I gave the explanation for this in my post "Plants and photosythetic bacteria were the driving source in the production of the O2 in our atmosphere but the water and oxygen atoms themselves pre-date plants."
1) No other planet in the solar system has the oxygen earth does in it's atmosphere.
That's a temperature/atmospheric density issue, not one of non-existence of water. Water exists in gaseous or solid forms in many other places. The post I was replying to was arguing that H2O couldn't exist without plants, not that liquid water didn't exist.
2) No other planet in the solar system has water like earth does.
It's not expected that they would, no other planet has photosynthetic life to produce the O2 required to fuel ozone production.
3) No other planet has an ozone layer.
Generally you don't. Where are you thinking that such a thing happened? The simplest way would to just add H2O directly until you had your desired amount of water. Assuming you are talking about mars your question should have been the reverse, where did the water go to leave mostly CO2 in the atmosphere. There are several possiblities, such as being frozen underground, or lost into space.
How do you make H2O out of an atmosphere that is mainly CO2?
Why do you think there were surface oceans of water at those conditions? Have you considered that the temperature and pressure on mars might not have always been the same as it is now? You predict that there were once oceans when you see large scale rock formations that are related to oceans.
How do you have oceans where the water boils at 50 degrees F and the normal temp is 70?
How do you have predicted oceans of water on a planet where water no longer exist, and there is no gaseous evidence in the atmosphere that it ever did?
How do you get ice caps of H2O where there is no water? Frozen CO2.
Who's lying? The info about mars you listed is common knowledge, available to anyone, and has been for decades. Do you think there is someone saying that there are oceans of water on the surface of mars currently?
So why would science lie to the public about mars? It's called lying in the tune of a trillion dollars for the mission to mars. How many people would lie for that money?
