Everybody's wonderin' what and where they all came from
Everybody's worried 'bout where they're gonna go when the whole thing's done
Nobody knows for certain so it's all the same to me
I think I'll just let the mystery be
( an old traditional )

The Vatican reports worldwide adherent percentages at:
19.2% Muslim
17.4% Catholic
33% all flavors of Christian

In the US we are supposedly 76.5% Christian.
