Because Earth's Gravity doesn't make things fall down, it makes things fall towards the middle of the planet. That goes for everything on Earth; its skies, oceans and people. Isaac Newton told us how gravity works, like how and why things fall towards the ground when you drop them, and how fast you can expect them to go when do. He also told us that gravity wasn't just about things falling towards the ground but rather all objects falling towards or attracting each other. This force of attraction is stronger for larger object, and Earth is by far the largest thing in our planet. So everything on Earth is held on by one of Earth's super strong gravity. Like a big ball-shaped magnet with bits stuck all over it, not just metals, but all kinds of things, like air, water, trees and people. That's why none of it falls off. Gravity is a force that is caused by the attraction of objects with mass. The planet Earth is very massive so we can feel its gravitational force when we are at or near its surface; that is why we don't float away. The Earth's gravity is pulling us down.

Space is not empty, or even flat, it's more like a fabric with lumps and dents on it
The lumps and dents are cause by objects like stars and planets in the fabric
Gravity is just objects rolling into dents in the fabric.
