you're probably more aquainted with a field that you can feel. Gravity. Gravity, like the electric and magnetic fields, is also a field. A field is a mathematical way of describing something that has values throughout all of space.
You are sitting on the face of the earth right now, you feel a certain force pulling you down. Now imagine you are in outerspace, you still feel a force pulling you toward the earth. But now, that force is slightly less. In fact, no matter where you are in space, you will feel a force toward the earth. (if you go out too far, that force becomes really really tiny, practically zero).
Since you feel a force everywhere in space, physicists use a description for gravity called a "field". It simply means that for every point in space, there is an associated force pulling toward the earth.
