Well, this is my take on it, and my theory is backed by the journal of factual conspiracy theories.
I haven't seen any evidence that Jesus existed as depicted in the bible. The chances are that he never did.
The purpose of all religions IMO, is to state a fixed reference point of morality, and how to conduct yourself in order to live a more fruitful life.
As in the previous mathematical arguments (which were moved), without a known reference point to measure against, there is no hope of reaching any conclusions or plotting progress.
The legal system is supposed to achieve a community standard, but it doesn't. In an increasing population, laws are constantly changing to do away with freedoms which were once taken for granted.
To a large extent, laws are designed to be changed.
In regards to Jesus, I find it of no surpirise that his word was never known until many years after his death.
Finding a living symbol for Christianity would've been nigh on impossible, so a mythical symbol was invented.
Together with a mish mash of known religions and concepts of the day, and some very good marketing techniques to spread the word, Chrisitianity
succeeded as a religion.
But this is not to say that I think that religions are a load of junk. I hold some in much higher regard than our legal system or poliitical system.
They've stood the test of time where other concepts have failed and I plan on devoting more time to reading the bible.
