Nice way of putting it. Yesterday morning my son asked how humans came to be and I ended up stuttering that perhaps at some point some molecule of unspecified complexity gained the ability to replicate at which point it became subject to natural selection based on descent with modification... You get the problem. Better say: It started with simple life and the best ones (sometimes more complex ones) ended up in the next generation. FFWD 3.5 billion years and voila. It's a bit of a lie because "what's life, what's before that, what's best, what's fitness" etc. But it works. I keep having problems with this though, but yeah, what to say to someone without any grasp of cells or DNA or "1 billion years", do even grasp it "correctly"??... Man, speak about rabbit holes. I didn't even start on evolution on the population level.. I see my son loosing interest during my explanation, while I get more and more enthusiastic. It's a hard problem.
