Looking for an example of a "story easy enough to tell" that everyone will agree "is just a story".
==================
Imagine if you will that "once upon a time" there were "arm humans" composed only of arms, and "Leg humans" composed only of legs and "Torso humans" composed only of human head and torso.
And suppose those individuals got together and started forming fully formed humans as we know them today, the result being the humans that we see today.
And we note that similarities are there - that the same sort of human skin can be found arm/lets/torso. We also note that the DNA in the cells of legs/arms and torso is sufficient to reproduce an entire human.
==================
regardless of the level of detail in story telling that I add to the story above -- it is pretty obvious that both atheists and creationists will view it as a "story easy enough to tell" and would doubt that it is to be taken seriously beyond "just a story".
I could even add "symbiosis" to the end of the story and it would not make it any more believable.
