Why is there gravity on earth?

Gravity is the gravity that all bodies and objects on Earth are subjected to.
Gravity on Earth is necessary so that people, animals and all inanimate objects can stay on it. It is thanks to gravity that people feel the mass of their bodies. The more a body is in mass, the stronger gravity acts on it. The phenomenon of sea tides is also due to her. In addition, in outer space, under the influence of gravity, all celestial bodies move in their orbit around the Sun.
