How is the Earth round?

I know this might sound stupid, but how the heck is the earth round? Is it a huge sphere that floats in space?
Also, humans don't fall out of Earth due to gravity, right?

Gravity is omnidirectional.Matter is drawn to the Earth from all directions.Primordial Earth was molten which allowed matter to form into a sphere.Earth has a molten interior.

Because the sphere is the simplest geometric form.

When the galaxy is formed, the material starts to get together and when it starts to get together, it starts making rotatory moving, making everything else moving like that. And when the movement is rotatory, things tend to be round (actually a little bit oval). That's why the Earth is round (slightly oval) and so is every planet, the shape of the galaxy is oval as well, sun is round like every other star. It's the most natural shape of things. The universe is probably oval as well (nobody knows).

Because the Earth was shaped by erosion and other landscapes, besides if the earth was flat we wouldn't have all these beautiful countries/states in the world that we do now! (Even though not all of the landscapes have been discovered yet!)

When the Earth was molten the rotation on the axis caused it to become spherical, all liquids do that.
Gravity holds EVERYTHING on the planet.

The earth is a triangle and people fall off the earth all the time. And this triangle is placed on Gods ***
