This question has plagued me for a very long time. I'm sure every one knows that everything that has matter has gravity, no matter how small. We also know of the 4 primary forces of the Universe, but what if there is only 3 with gravity being made by the attraction of electrons to protons that are part of a different atom. The more atoms you have, the more "attractive" you are. We currently do not know what makes gravity, so, is this the possible source of gravity?
