the theory that we're on a spinning ball, and held down by gravity so insanely strong that it can hold every skyscraper on earth to the ground like glue but is instantly conquered by a balloon...makes no logical sense

The earth is moving, there is an upward vector. Buoyancy shows us the direction of the movement and density shows the source of the movement.
You can feel this motion every day, it's your weight.
I like hearing your ideas on flat earth even though Iβm not a flat earther myself. But this one is obvious. Helium is less dense than air. Something youβre forgetting is that a balloon full of air does in fact drop to the ground.
