They claim outer space is a vacuum. Elementary school science counters that. If space is a vacuum, the air on earth would have to be contained by a protective barrier. The moment that barrier were pierced by an object leaving earth for 'outer space' our atmosphere would be sucked away in an instant! Just to be clear i believe NASA has lied to us about everything.

Your own logic shows that the Earth is not contained in a impermeable bubble.

On Earth, air pressure decreases with increased altitude. If the Earth were inside a containment vessel (such as the firmament) the pressure would be constant at every altitude.

Pressure relative to altitude is consistent with a gas under an accelerating force (gravity).

Believing that the Earth is a sphere does not require also believing in the Heliocentric model.

Nearly every major University relies on the heliocentric model in Math, Physics and the Sciences. There's gonna' be some big holes.
