Well, that is not entirely true. When an object is propelled upwards with a force that is equal to or exceeds escape velocity, the object will not come down. If its speed is less than escape velocity, then the earth's gravity will bring it back down.
Each planet has its own escape velocity which is dependent upon the planet's mass. The greater the mass, the greater the gravitational attraction and, hence, the greater the escape velocity.

Gravity or if you prefer, weight, is what makes things come down. The saying became popular before we were able to get things into outer space. It came about because no matter how far ancient people could throw things up, they always came back down. You can take it a step farther and realize that sooner or later, do to disaster, erosion or just time, anything that mankind has built is going to fall down, sooner or later.

That would be gravity caused by the revolution of the earth!
See what Sir Isaac Newton and an apple caused!

I am not sure that this is a question of sufficient gravity for me to answer it...
