Which goes back to the last two points. The theory is a theory as to what happened, not why it happened. It is no different that the scientific answers for how the universe was formed. Science can observe what happened and even how it happened but it can only speculate between random chance, directionality or some combination of the two.
Suppose I go on a random walk, making a random choice at each step. You happen to be watching, though you are unaware that I am making random choices. If you describe my walk, you will very likely describe it as directional.
Sure but it would only be a best guess as I have no concrete evidence as to whether it is random or carefully planned.
Yes, I believe in guided evolution, or at least designed evolution, but I'm not arguing for that. I agree that is just my opinion but so is the view that there is no design or guidance in the evolutionary process.
