Hey, believe whatever you want. Here’s something for you to puzzle over, Mars is about ten percent the mass of the Earth, and yet...
“The average pressure on the surface of Mars is only about 7 millibars (less than 1% of Earth’s), but it varies greatly with altitude from almost 9 millibars in the deepest basins to about 1 millibar at the top of Olympus Mons.”
