I was wondring where does this words come from and all the people now saying it even the Arabs,

What does it means?
Does it mean something relate to the BaBa of the Christian?
and if its mean "God be with you" where this words come from this meaning?

i hope u get what I'm wondring on?
Hey moon,

interesting question indeed - the etymology dictionary does support your thesis:

"bye - shortened form of good-bye. Reduplication bye-bye is recorded from 1709, though as a sound used to lull a child to sleep it is attested from 1636."

"good-bye - 1591, from godbwye (1573), itself a contraction of God be with ye, infl. by good day, good evening, etc."

Hope I could help you out.
