Why can't you just float around space

We float in space because there is very little gravitational force acting on them. Gravity is a force that is caused by the attraction of objects with mass. ... In space, you are very far from Earth's center of gravity (other planets have gravity as well), so it doesn't pull very hard, and we basically float around.

We can float in space.

Explanation:

We can float in space because of gravity. Gravity is the force that attracts anything towards the centre of earth. We can stand, walk because of gravity. Even if we jump, we come to the ground because of gravity. In space, there is no gravity. That's why, we can't walk in space and everything floats there.
