It is very clear that the Earth neither heats nor cools outside the sweet spot where life thrives.
Billions of years of evidence.
There is a system that cools when it is too hot, and a system that heats when it is too cool. I believe the answer could be shown by anyone with a reasonable intelligence that since water vapor is 95% of the greenhouse gases in the atmosphere, and abouty 400 times more effective in heating or cooling the planet than CO2, we might look to the “easy” answer on this one.

Yes I think you’re correct to suggest water is a very dynamic factor which the experts with an agenda tend to overlook in their climate models. It’s as if they’re deer in the headlights of CO2, and can see nothing else. There are many other factors as well which I doubt they pay enough attention to. To make predictions without real experimental data is to go backward almost 400 years, before Galileo invented the scientific method.
The reason that the absorption of heat by water vapor is ignored is that the powers-that-be cannot gain control. OTOH, CO2 is a feature of manufacturing and transportation. Control CO2 and you control everybody and everything.
On a clear night, imagine two cars: One, parked overnight in the street; the other, under a carport. On occasion it will be observed that the car in the street is covered with dew while the car under the carport has no water droplets. The car in the street has lost radiant heat to space and cooled enough to cause water to condense. The car in the carport cannot “see” space, so it’s heat loss is less; hence, no dew. The effect is called black body radiation. The car in the street lost heat energy to space while the carport prevented the loss of heat from that car.
