anjohl: Regarding quantum mechanics, show proof of a particle existing in multiple locations.
Strictly speaking, quantum mechanics doesn't say that particles exist in multiple locations simultaneously. It states that the position of a particle is a fundamentally probabilistic observable. The momentum and location of a particle cannot both be known with arbitrary accuracy (not even in principle, with a lower bound given by the so-called uncertainty relation). Admittedly, this does sound strange and unfamiliar, but it can be directly observed in experiments. In the famous double-slit experiment, particles like photons or electrons can produce interference patterns which demonstrate the probabilistic nature of the particles' wavefunctions.

There are no "sub-electron particles" as far as we know. Electrons appear to be fundamental. Protons and neutrons, on the other hand, are extended structures composed of quarks and gluons. The first experimental evidence for the existence of these subatomic particles came from deep inelastic scattering, which is the scattering of high-energy electrons (or muons, neutrinos) with protons and neutrons. If the electrons have sufficiently high energy, their wavelength is short enough for them to penetrate inside the proton/neutron, allowing us to probe the internal structure of the nucleons. By measuring structure functions in deep inelastic scattering we determine that electons scatter off of charged pointlike particles with spin-1/2 inside the nucleon (we call these "quarks").
Here's a nice introduction to deep inelastic scattering with some experimental plots:

It has some very concrete real-world applications that you seem to be completely unaware of. The computer you are using would not exist without it. The invention of the transistor (and the entire field of semiconductor electronics) is due to quantum mechanics. The same is true for the laser. All of the chemical properties of atoms and molecules are due to quantum mechanics. I could go on, but I fear that I'm wasting my breath.
anjohl: It's all so arrogant and hopeful. I bet if you had to bet your life on your convictions, people would apply the term "theory" properly for a change.
You know what's really arrogant? Casually dismissing a body of knowledge that has been studied and tested by millions of people for nearly a hundred years without even making the slightest effort to understand it.
