Remember, the ancients weren't as far removed from Adam and Eve, so they had super-vision. They had retinas stuffed with so many rods and cones that some of them would just leak out. Which was kind of gross. But they could see that Mars was red, and they probably even had heated discussions about whether Pluto was really a planet or not.
"Well, evolution is a theory. It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts don't go away when scientists debate rival theories to explain them. Einstein's theory of gravitation replaced Newton's in this century, but apples didn't suspend themselves in midair, pending the outcome. And humans evolved from ape- like ancestors whether they did so by Darwin's proposed mechanism or by some other yet to be discovered."
