The universe, physical and otherwise, one dimension or multiple dimensions, was created and constantly changes. We can experience only a very small portion of it in any given lifetime and we use our free will to determine which portions by the decisions and choices we make in everyday life. Each decision moves us towards possibilities and probabilities and away from others.
This scenario can work the same if everything we can ever experience already exists or if we are creating it as we go along, IMO.
Very interesting insights, Consort. I think this puts you in the Erasmus Darwin camp of evolutionary theory, and decidedly not in his son's. The former recognizes and is open to intellect and free will; the latter is relentlessly deterministic, "blind." It has been observed that Charles Darwin's theory is the secular twin of the Christian dogma of predestination, as it is commonly understood.
