[glow=blue,2,300]Only one problem with that LB.. The initial race that was aware of the force was a species of "for the most part" pacifistic monks. They had learned so early on in their ancestory that going down the path of violence for the sake of violence was a path that doomed themselves.. and did not make the mistake that the Sith eons later would make.
So among the "Jedi" there was no real "Unenlightened Time" which blows the speculation right out of the water.
That plus the fact that even back when the lightsabers required a power generator built into a belt and the blasters were pulse wave weapons, the Jedi still used the sabers, as opposed to the pulse wave blaster as their weapon of choice.
The Jedi even back in their earliest dawn were never truely meant to be warriors. Yes, they do practice various arts of self defense as their roles as protectors of the Republic require them to enter into situations where diplomacy, while hoped for, is not always acheived at which point violence is almost always the resulting outcome.
