The Earth is an oblate spheroid, not a perfect sphere. This shape allows gravity to pull objects toward the center evenly, which is why people can live on all sides of the Earth without "falling off."
And gravity pulls everything toward the center, which explains why people can live "upside down" in different hemispheres without falling off.
And what he said about water, Water conforms to the shape of its container due to gravity,
Earth's gravitational pull keeps oceans and lakes from "falling off" the surface, allowing water to curve along with the Earth’s surface.
At the end of the day, when there is a lunar eclipse what do you see? A round shadow that Earth casts on the moon.
And the earth is spining and you ain't hovering because of relative motion & inertia.
And that spinning motion, gravity keeps you grounded and gravity is stronger than that motion.
