Sorry to hurt your feelings, but evolution has never been proven. It is just a theory that has atheists beating their heads against the wall for decades. There has never been a fossil proving evolution, so why do you make up these tales? The Bible doesn't specify how old Earth is, so I have no idea why you keep pushing that part.
As far as the comment of 80% of the country believing, I would have thought that you would not have difficulty understanding what was meant. But, I will type slow so that you don't miss anything. Approx. 80% of Americans beleive in GOD. Since there would be no point in evolution if they believe in GOD, then it would be presumed that they believe in God's creation of man. And since you can't find any fossils to prove that man evolved from anything other than man, then man had to come from somewhere. Perhaps you believe Earth was seeded by aliens?
