None dare call it legend

I'm beginning to wonder how many religious founders actually existed?  Did Jesus really exist, for instance? Moses obviously didn't. 

How many Christian saints are purely legendary? Did Sta Lucia, St Martin and St George really exist? 

What about the Buddha, Lao-tse or even Nichiren? 

Muhammed presumably existed, but how do you know that's the right Quran you' re reading? Exactly. You don't.

What if it's all a lie? An enormous lie...
