      The issue with your model is this: what exactly is the relation between epigenetic systems and the origin of functionally complex structures such as eyes, brains, hearts?

      There are two considerations:

      1 If epigenic systems really produce complex adaptive structures, they must themselves be complex, which in itself needs an explanation. (Other epigenetic systems perhaps?)

      2 If on the other hand epigenic systems are relatively simple, they can't produce complex adaptive systems.

      So either you explain complexity with more complexity, or you explain complexity with simplicity. Neither makes sense.

        Yes, that is true. It is interesting to note that, for that very reason, speculations about time travel are wholly fanciful, because it would be impossible to travel to a place that DOES NOT EXIST, even with the latest and most advanced of time machines!
