I really do not understand where you come up with "B" came from "C" as part of my comments. Nowhere have I made such claim. On the contrary, I've stated that the ToE postulates that "B" and "C" came from "A", nothing more.
Using the terms "monkey" or "ape" was nothing more than a parsimonious discriptor and not meant in it's literal transformation.
While I understand the tenents of ToE, that doesn't mean that I agree with all the claims of ToE.
That imprecise (and very inaccurate) use of terms is what I'm taking issue with. Your original statement that the theory of evolution is a "belief that modern human started off as a monkey, and then evolved into what we are today" is fundamentally flawed and badly misstates the truth.
Your parenthetical "if nature decided that modern man was superior to the monkey, then why are there still monkeys?" suggests to me that you misunderstand the basic nature of evolutionary ancestry.
