All Hail the Parallel Postulate

I was reading that John Playfair in 1795 was able to reduce the parralell postulate to more acceptable terms:

"Given a line and a point not on the line, then one can draw one and only one exactly one absolutly one parallel line through the point parallel to the given line." This is more elegant, but it did not give his reasoning. May someone explain if you know this?

It makes me want to laugh, people were working of simplifing the parralel postulate for close to 2000 years, and the result they got was that you can draw parrallel lines. If a non-mathematician would hear of this he will think we are insane to try to simplify something so obvious like this!
