We live on the planet Earth, which is a very large, massive object that exerts a strong gravitational attraction; as a result, we have weight and we do not float away into outer space.
The precise mechanism of how gravity works is still under discussion by theoretical physicists. Einstein thought it involved the bending of the four dimensional space-time continuum, but there are other theories as well.
Because the forces of gravity are able to hold it down.
Hold both of your arms out to the side for as long as you can. Eventually, you will feel the pull of gravity pulling them down.
Please take a look around you, and do some experimenting. If you hold an object in your hand and let it go, will it normally fall up, or down? The answer is down. gravity pulls you down. THERYAGO.
If pool/lake/ocean water floats up: then no, gravity does not hold water. If pool/lake/ocean water does not float up: then yes, gravity does hold water.
It keeps your feet on the ground, probably the most important thing. If you play football you rely on gravity to bring the ball down after you kick it. On a boat you rely on gravity to hold the water down so that your boat floats nicely. When you get out of bed and stand up, it's gravity that allows you to do that. Pretty important?
Yes

they wear them to hold them down because there is no gravity in space they are called gravity boots

If there was no gravity your eyes might have the chance of your being pulled out of your head if not the proper gear is with you also would be lifted from the ground because you will not have the gravity to hold you down
Air has mass, and gravity pulls anything with mass. The gravity of the earth "pulls" air down towards it's center.
Because it doesn't have enough gravity to hold the atmosphere down? :D
Hold the Gravity!! or Hold up the Gravity!!
No. Gravity is a force, not a substance.
Because earth doesn't have a tip and gravity hold everything down.
No the weight of the ball will slow it down then gravity will take hold and it will fall to the ground
