If we do not understand dark matter or dark energy how can we theorize that this particle exists? Unless of course they (matter and energy) have no effect or relationship to this particle in which case I am an idiot!!

Because we have observed them through their effects in nature.

Dark Matter - Distant galaxies have a spin velocity that does not correlate with their observable mass, leading to the conclusion that non-observable mass is the culprit.

Dark Energy - The universe is expanding outward at an accelerating rate, leaving us with the question "why?" Dark energy is a placeholder for the answer to that question.

In other words your saying it's an act of god.
Ok back to square one.

Funny, I don't recall saying that. Those are two scientific mysteries, as in, we don't know the answer yet. "We don't know" is not the same thing as "god did it."
