No, I assume you're ignorant because you refuse to acknowledge facts that don't fit your preconceived notions. You ignore knowledge that you don't like because it doesn't support your chosen worldview. That's willful ignorance in the face of potential learning.
Words mean things, don't they? Or are those "in the mind of the beholder" as well? You already admitted that you don't believe in facts, perhaps you don't believe in words either?
You apparently choose to believe facts as you interpret them and that's your right. Many, many people don't believe we descended from anything other than humans. Why does that bother you so?
