Interesting thoughts so far.
Some choose to go for the christian ideas that the creator is in the form of a human male. Some decide that the creator would be an entirely different form of which we couldn't conceive.
What I think is this, the concept of a creator was created by humans looking for an explanation to life, the general concept will be the same for all, there is someone/thing that made the world we know, the specific ways this creator made the world is different to each person though many decide, rather than to think up their own idea, to follow the idea that were made before them and was either told or chose to believe it as right and when enough people do this, the ideas on the specific details of the creator become a religion. The trivialities such as how the creator looks is different for each person, even to those in the same religion because the creators appearance is created in our minds. I would say that because of this, the creator looks like whatever we want the creator to look like.
