I am inquiring about the personal nature of the entity, or entities in question. Get it? "Personhood," not "cause" or "means."
An intelligent entity by definition has personhood. Get it?
But what you are really getting at is whether the objections raised by "Intelligent Design" advocates require an entity to resolve them, assuming that the theory of evolution is inadequate to do so. No, they don't, but then you wouldn't have "intelligent design" but rather something from the options in the excluded middle that ID advocates ignore. By example: panspermia.
