The average person in what century?
So you don't know nuttin' 'bout no science but you know your granddaddy weren't no ape. Science has left details of the history if you ever do want to reconstruct how it got to where it is.
It is OK to decline to review this. The main point of educating yourself thoroughly in a scientific specialty is to prepare yourself for a career, bringing yourself up to the edge so you can push the envelope in your research. People who don't intend to be scientists themselves will more likely confine themselves to layman-level presentations.
However, declining to learn even the first things about science somewhat undercuts your claim to knowing that science has everything all wrong.
Grow up. If your statement above is any indication of your ability to read, comprehend, and critically assess an issue, then I suggest you stay away from scientific pursuits until you have the capability to refrain from overgeneralization.
