Is there anyway we can convert the asteroid belt to a planet without destroying Earth?

In a sense, such a planet already exists. It is called Ceres, which has ~1/3 of the total mass of the asteroid belt. If you could add all of the other asteroids to Ceres, it would make a body ~triple the size, which would be only the cube root of 3 larger in diameter, or ~40% larger than current Ceres. I can't wait until the NASA space probe DAWN arrives at Ceres in 2015.

Good...It might be possible. Although a couple tips make it unlikely. 1.There are not ample asteroids within the belt to make up a planet of even the dimensions of Mars, let on my own Earth. And a planet would must be at the least that massive to have existence on it. 2.The asteroids do not appear like they all came from a single enormous object. They wouldn't have that 'sharp, edged broken' appear to them. 3.If a planet was once there and was once destroyed, we must see asteroids all over the place the place. The asteroids would no longer simply unfold out in a perfect disk. Four.To smash a planet would take a huge amount of energy/force. This would have effected the orbits of the opposite planets(we might see a 'wobble'). 5.If the planet used to be destroyed, how would the life get right here? The blast would have killed all of the life.

What do you mean "without destroying the Earth".

Why would converting a ring of asteroids into a planet several AU away in any way danger our own planet?

Anyway, to answer the question. No, it would take nearly a billion years to become anything more than a molten lump of rock. And, the asteroid belt is thinly populated, not at all like what you see in the movies. Imagine 1/4 the mass of our moon, spread out in bus size rocks spanning the entire solar system, with 1/3 of that mass in just 4 small dwarf planets. If we were to somehow change the orbits of these planets, which, with our technology, require a fuel tank the size of the body themselves, we could cause them to crash into each other and merge, thus creating a much larger, maybe moon size dwarf planet.

The total mass of the asteroid belt is 4% of the Earth's Moon, you could only create a small moon with the asteroids. But you could build a lot of O'Neill Cylinders, Bernal Sphere's or Stanford Torus's out of the asteroid belt.

The largest asteroid, Ceres, has a diameter of about 950 km.

Adding ALL the other asteroids of the asteroid belt to it would not even double that diameter. Which would be comparable to our moon at 1737 km diameter.

The 4 largest asteroids combined have about the same mass as all of the other smaller ones.

If we did, it would be an awfully small planet! The total mass of the asteroid belt is roughly 4% that of our Moon. Even if we could (which we can't) the gravitational field of Jupiter would rip it apart again.

No. Asteroid belts cannot be made into planets by humans. Humans can't make planets.

No.

The presence of massive Jupiter in a nearby orbit is what has kept them from coalescing into a single body already, and it will continue to do so.
