firmament
If the reason we have pressurized air on earth is because of the firmament/dome around earth then why does air pressure decrease the higher elevation you go? If the earth was pressurized in a dome there would be equal pressure everywhere which is not what happens.

" If the earth was pressurized in a dome there would be equal pressure everywhere which is not what happens." First we do not claim a dome but i understand your point. And no, that's a baseless assertion, you might be aware that gasses have their own density, they don't have the same density. Thus there is a density gradient, and when there is a density gradient, there is a pressure gradient. Ever heard of a propane tank or a diving tank? Well, pressure is much higher at the bottom due to the desnity of the gas above. This is called density stratification. https://youtu.be/PXnaVvgaYY8?si=4FFxd1ytBlc3Nc4B
Because that's expected in a contained environment where the majority of the gas Is produced on the surface
the only way to have a constant pressure in any volume, you would need a constant temperature in the volume. we don't have that on earth.
then as pointed out there are cycles happening at the surface, nitrogen carbon water etc
