Just
how did the perfect mutation occur that allows for things such as our
senses,
immune system, etc?

Not "perfect" mutation, dear - multiple mutations which are then
preserved during selection.

So just how are these mutations "preserved during selection"? Is there
some
force that "knows" when to keep the desirable traits and reject the
undesirable
ones?

It is impossible for these things to just "happen". It is magic pixie dust
or
what?

Well, I could begin to explain mRNA, tRNA, transposition, insertion,
and deletion, but obviously it would be lost on you...

It's just a theory anyway so why bother, right? I don't think you understand
it or can explain it.
