Where did the light particles come from?

They are quantum exchange particles between two charged
particles.

What are they composed of?

They are modelled by Maxwell as "EM fields". They are a series
of (non-propagating) virtual photons in QM.

When they move. What do they move through?

The Universe in Maxwell, and they don't move through anything in
QM.

Einstein said,

He died in 1955. There is no religion with His name on it.

"Light is pure energy" and "Energy is space in
motion." Therefore, a light particle has be
composed of energy waves.

No.

Waves of what, if not aether?

Ripples in the Universe, in one model.

Relativity theory says they have to be
something substantial. Q.E.D.

No. In fact, it says they cannot have any substance at all.

No matter what you call it,
it's still aether, or empty (of form) space.

There is no empty space.

So, the MMX proved nothing.

It disproved an aether that was unique to light alone.

Since the aether is the root of all earthly
matter

Impossible to prove.

and had to be traveling through space along
with the Earth, how could the MMX prove it
wasn't really the medium of light originating
from the Earth?

It disproved one of three classes of aether.
