To paraphrase Sheldon the Wise, there is no essential difference between the belief that the sun's apparent position relative to arbitrarily defined constellations at the time of your birth somehow affects your personality and the belief that a magical man in the sky created the universe and everything in it, only to be so offended by your failure to show up at his Sunday gathering that he will make you suffer excruciating pain in the fires of Hell forever and ever with the sole purpose of petty revenge. So none should be made.
