What is God's First Name? What Makes Us Christians Or Anyone Else So Right And Everyone Else So Wrong?

Why is it right to call God Elohim and not Allah? Why is it so right to allow a term such as "The Great Spirit" but not "The Great Architect"? Do you really think God cares rather you call him Jehovah, Allah, Elohim, The Great Spirit, Buddha, Mohammed, Jesus or even Flying Spaghetti for that matter? What makes us so right and everyone else so wrong?
