Did you know that humans have about 2500 transcription-factor genes, which construct the roughly 100,000 different kinds of protein that exist in our bodies, or that the number of different possible settings of those genes, if they were simple on-off switches, is 10750, compared to the 1080 particles in the known universe?

But much worse is that people have seriously been considering heliocentrism for many centuries before Copernicus. Aristarchus had proposed a heliocentric model in the 4th-century BC. It had generally been considered wrong, but not "mad." (And wrong for scientific reasons: Why, for instance, did we not observe stellar parallax?) And when Copernicus propose...
