If you place two mirrors directly on top of each other what exactly happens? My physics teacher says that it will create a perfectly black body?

Facing each other?
You get a lot of reflections (assuming a light source). If not, it's no different to anything else in the dark.

In order to see light, it mst travel through our eyes correct?

What exactly do we see? Is the light we see just individual photons traveling from a source towards our eyes?
If so, say we set up an experiment where 1 photon is traveling through space past two observers. Also, say these observers were small enough to see the photon. Who would see it?

For you to see anything a photon (in reality MANY photons) must enter your eye, strike a specific molecule in your retina and cause that molecule to change shape. This sets off a chain of events that eventually causes your brain to "see" something.
You couldn't SEE a photon. The process of seeing involves absorbing photons that are emitted or reflected off of other objects and absorbed in your eye. Since nothing can bounce off of a photon, there isn't anything to see. It quite literally doesn't look like anything.
