Yes that is the crux. Implicit in the notion of evolution is that things are getting better. They are not. You cannot evolve to your cause. Evolution is just going uphill. Step back and look at the rise and fall of species, of empires, of you and me. Everything rises and falls.
As JC is supposed to have said "dust to dust" or as it says in the Tao Te Ching, "the Self watches as the Ten Thousand Things rise and fall". Or another of JC's "Before Abraham was I am"
Not denying the state of Enlightenment, God, i.e. realising the cause. Simply that the notion of a limit becoming limitless is impossible.
