Alisa, comeon, this an easy question for you...is it your belief there is no god or God or do you have proof that eliminates "belief"
But back to your question's extension.
Well, first I would ask you are you referring to the Bible. I assume that is the case. If so I would tell you that I am not a literal Bible believer. However, if it was the Bible I would ask you for the reference so I could show it to a Bible person to see if your reading was correct and probably refer you to that person.
But in summary, if I could not find any evidence of the purple planet and given it is supposedly a local planet, then an entry in the Bible would not make me believe the purple planet was orbiting our sun.
