Psalm 137:9

[Huggy Bear]

"Liquid water is just condensed gas."

Huggy, everything that can exist in a liquid state below its boiling point and above its melting point is just condensed gas.  It's technically correct, but like with all of your perceived gotchas, utterly meaningless.  For starters, please remember that you're talking about a layer of liquid water in the atmosphere, not water vapor.  Also remember that your example is so unlike earth as to be a meaningless comparison.  Think about why liquid water couldn't be an atmospheric layer here (because I'm sure you're going to miss the mark, here's a couple of hints: rain, and the melting points of nitrogen and oxygen).

Regarding water on earth, scientists believe it was deposited via comets, asteroids, and meteors, however there are some studies now suggesting that at least some of it formed inside the mantle due to the proper chemicals being under intense heat and pressure (https://www.newscientist.com/article/211...he-mantle/).  Once again, science is a process, not a religion, so sometimes answers change.

Regarding abiogenesis, you're right, there's no example of it happening.  However, there's no example of your god actually creating life either, and it's far more rational to believe that the origin of life is some as-yet undiscovered natural process than the deliberate workings of a needy god.

So, to conclude, no, it's not plausible that earth had an atmospheric layer of liquid water.

*emphasis mine*
Show me where I stated that the water was in liquid form? I thought I made it perfectly clear that the water could of been in any form other than liquid, I don't know... I wasn't there.

Water can take forms other than liquid...

Not to mention that the Bible states that a mist watered the ground.

Which makes your conclusion pretty much irrelevant.
