A friend of mine is a full-blown conspiracy nutter, and based on the small amount of stuff he has liked/commented on Facebook I am not surprised that Trump's "Obama created ISIS" line resonates with people. That's pretty mild as accusations go, what with so many who are convinced that Hillary was running a child prostitution ring out of a pizza shop.
"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."
