What makes God an extraordinary claim?
Depends on the theology.
Take the Christian god, First, many say [he]'s omnipotent, omniscient, omnipresent and perfect. (If anyone knows how [he] got that way, let me know ─ I'd like to try it.)
The trouble with these qualities is that they're phrased as absolutes, and absolutes tend to have the same problems as infinity puzzles do. You can show eg that 2=1 so easily that they have to invent special rules to stop you (not unlike the rule, 'No, you simply may
not divide by zero').
So a real being with such qualities would indeed be extraordinary. Extraordinarily so.
Second, [he]'s also supernatural, immaterial, &c. Since those words have no actual denotation, 'supernatural' means [he]'s imaginary, and 'immaterial' means [he]'s non-existent.
So a being that was simultaneously real, imaginary and non-existent would also be right up there on the extraordinarimeter.
