You know why anti-gravity aircraft exist? Because gravity was just a theory.

Walk off a cliff and find out mate.

I'd fall. Not because of gravity but because my body density was greater than the air surrounding it.😎
If it was about relative density, things would not fall at the same rate ignoring variable wind resistance, 9.8ms2...
Things of different densities would not fall at the same rate.
