Santa and Satan

Hey Bloggers, I know it's not Christmas or the end of the world yet, but I can't wait for Christmas or the end of the world to roll around to blah blog this thought I have. I want to ask someone, or anyone who may be reading this blog, why does the word Santa have the same letters as Satan? Any why do both of these characters wear red, white and black and are mythical and magical figures that one has never really seen, except if someone dresses up like them. And why is Satan the opposite of Christ, who is Santa at Christmas? And both of these characters are bearers of light and gifts and are able to change forms like angels. Are they both deceivers also? What is the meaning of these two figures relations. Does Wikipedia have an answer for that.
