Cweusly, "Who Was The Creator?" is in fact a loaded question. It presumes that existence is the product of a 'who' rather than a 'what', which leads immediately to a contradiction by implying that someone can exist apart from the means and process of existence that makes 'anything', let alone 'anyone' possible.
Such a contradiction arises from the mistaken belief that consciousness can possibly proceed that which gives rise to the process of consciousness by means of a complex highly evolved being by virtue of the preexisting universe in which the means and process of conscious became possible and emerged. To have a consciousness, one must first be conscious of the existence from which consciousness arose and to which consciousness applies. To be conscious of nothing is a contradiction of what it means to be conscious. There must first be something, existence, before there can be someone, a being conscious of existence.
