Why Gravity is important?

Without gravity the sun woulden't pull the planets in allowing them to, orbit tthe sun.Without the gravity of the sun there would be nothing to stop us from flying in the darkness of space. Without gravity of space the panets woulden't be existed.Also without gravity the solar system woulden't hold together.Lucky god made gravity because without gravity the planets would just drift away
How gravity works?
Every time you jump, you experience gravity. It pulls you back down to the ground. Without gravity, you'd float off into the atmosphere -- along with all of the other matter on Earth.
You see gravity at work any time you drop a book, step on a scale or toss a ball up into the air. It's such a constant presence in our lives, we seldom marvel at the mystery of it -- but even with several well-received theories out there attempting to explain why a book falls to the ground (and at the same rate as a pebble or a couch, at that), they're still just theories. The mystery of gravity's pull is pretty much intact.
