I want to know exactly how it looks, what color it is, and how it behaves in every set of circumstances. All atoms consist of a central nucleus around which orbit the electrons at distances that mean that most of an atom is empty space. Furthermore, although I know the proton and electron are made of subatomic particles, I want to know what the subatomic particles are made of. I thinks this answers your second question. We are not lacking in understanding here, either.
Electrons are fundamental particles.
Protons and neutrons are each made of three quarks. The mathematical basis for this theory is solid. The observational evidence was to have been provided by the Superconducting Supercollider. This massive particle accelerator was to have been built near Waco, TX, but Congress, in its infinite lack of wisdom, canceled funding for the project. Yet, I think you have drawn a line between religion beliefs and scientific knowledge that you may not allow yourself to cross.
