I'm trying to imagine a parent discussing the issue of atheism with a child and I keep seeing a grownup and his kid just sitting there for a short time, saying nothing. Finally they both nod, the parent says "glad we had this chat" and they both go about their day.
"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."
