Could gravity just be an attraction between particles in objects, like a weaker form of magnetism?
Since magnets are polarized, they have a strong attraction, but since charges are spread evenly through normal matter (not magnets), they might just attract one another proportional to the amount of mass, since the charges are spread evenlty throught the objects that share a gravitational attraction.

Also, is gravity necessarily a distortion of space?

Well, we know that gravity and acceleration exhibit similar forces. That is, falling towards earth is essentially the same as earth accelerating towards you at the same speed.

I've often wondered what the actual forces are that give two bodies gravitational pull. In other words, what is gravity made out of. What you say could be true, but the charges you speak of already have counter-charges within that same body of mass.

Another interesting phenomenon that Einstein talked about is something he referred to as "spooky force." What he was talking about was the immediate effect gravity has between objects separated by large distances. In other words, unlike light, which takes some time to travel from point A to point B, when an object in space was moved, the effects would be felt immediately by the other object. Therefore, the communication between those two objects appears to travel faster than the speed of light.

The attraction of one particle to another for other than electrical or magnetic reasons is a description of gravity, the part that you unclear on is that the bigger the clump of particles the more attractive is the gravitational field. A massive object curves the space around it is an accepted fact.

Gravity is a separate force from magnitism or the force of charges. it has nothing to do with electromagnitism or any of its cousins. Newton showed that gravity depends on Mass and nothing else. However its possible that gravity is related to (newly discovered) Dark Energy - the force causing Galaxies to accelerate away from each other in some negative form.

Einstien said that gravity warps space and time and it was later proved correct when measuring stars at the rim of the sun.

For thousands of years, all the great philosophers abhorred the idea of force at a distance without a particle to carry the force across the distance. Einstein decided it doesn't matter if there is a particle or a medium; if the formulas accurately describe the effect, we'll just pretend that it is a property of space. The warping he described is in 4D space-time; it's pretty hard to wrap your 3D mind around it.

Gravity warps space - since light is massless and bends near a large object, there would be no charges or mass to support your theory of another attractive force.
As a side note, did you realize that a light beam on earth is not straight? In bends in an arc toward the earth's surface equal to the arc in a circle with a one light year diameter.
Obviously, this doesn't detract much from measurements and leveling devices which use a laser beam for accuracy.

This is one of the fundamental theories of physics or Unified field Theory that you're talking about. There are only four types of forces Grav, Electromagnetic, Strong and Weak. The last two are nuclear level forces. Physicists have proven electro-weak force which means that the origin of electromagnetic and weak forces are same. They are still trying to find the link between electro"magnetism" and gravitaional forces.

We simply don't know.

There is a theoretical particle called a graviton, but it has never been found yet.

As for space being warped. We don't know, it's just a logical way to look at gravity.
