Those that believe in Creationism are an excellent example
of the process of evolution at work.
Mankind has been capable of rational thought since time immemorial.
However it has always been tempered by the Irrational.
Including the belief in Gods, magic, ghosts and the many other figments of his imagination.
While invention and imagination are vital components of an evolved mind.
we have reached only a stage in development towards a fully rational mind,
A mind that can distinguish between make-believe and reality.
We are at that stage of evolution where there is a demonstrable difference between those have made that step.
and those that have not.
Creationists are a clear example of those that are being left behind in this evolutionary race.
Most have minds that are fully equipped to think rationally, and see make-believe for what it is.
but they choose not to do so.
Fortunately the process of evolution is continuing as always, and the direction is towards rationality.
This of course does not answer the question as to, if there is or was, a creative force that established the universe.
At this stage we have no means of knowing. but it certain that our attempts at defining such an entity have failed so far.
