We must believe that Unix is a part of Linux on faith alone. This is what we refer to as a "religious mystery," ala the Holy Trinity. Thus, to ask how can Unix and Linux be one in the same is equivalent to asking how the Father, the Son and the Holy Spirit can be one, yet distinct. I, for one, need no other proof than the Divinely Inspired testimony of McBride, and anticipate the coming day of His own Passion.This is referring to the testimony of Darl McBride in court that Linux is Unix System V, which of course everybody with a half competency in programming knows isn't true, and even the other honchos in SCO admitted in court wasn't true.
In any case I thought I would include it here because it makes a valid point about the doctrine of the Trinity. A doctrine that is nowhere in the Tanak, or even the New Testament, and yet millions of people believe it to be true, based on nothing other than the word of the Pope, or their Pastor.
