The concept of an avatar is much broader than that presently given it. There are real avatars residing in each of us. They are the mental representations of people we know. For instance, you may have a mental image of your father. You may think of him and create mock conversations using the information you possess about his personality, character, history, appearance, prejudices, etc.
This conversation is not entirely artificial.
It is as genuine as your father's avatar is true to life. That avatar is a permanent resident of your mind and will never leave or cease to give advice or critcism about any situation you might find yourself in.
Even when your father is dead, his avatar is still there. The full extent of his presence is dependent on how well you maintain it (by thinking about him). In fact, all the people who have ever lived on Earth contribute some piece of themselves to those avatars inhabiting your mind by being passed along (in modified incorporated versions) from generation to generation.
What then can be said about an avatar who has never actually lived?
In general, such avatars are too poorly drawn to make secondary realistic images of. It's like making a copy of a copy ... or worse ... a copy of a copy of a copy. Each rendition gets more grainy and unrealistic. If you've ever jpg'ed a jpg you know that this just ain't gonna' work.
Imagine your internal avatar of ... hmmmm ... Bambi. The character itself in the original movie has much too little detail to make a successful avatar out of. Whereas, your interactions with your relatives may span decades and contain gigabytes of condensible information.
This is not the case with the greatest of all avatars ... Jesus.
Here is an entity made up in the last half of the first century to embody the Christian faith. His reality became part of the official dogma over time as more details of his philosophy solidified in the minds of true believers.
Until I began to look around on the web, I used to believe that this man actually existed (although in a much reduced form, i.e. entirely human). Now I find that there is no independent documentation of his existence and his own alleged followers - Christians - fail to make mention of him as a flesh & blood entity till the second century [ not including the original "prospectus" ... the gospel according to Mark ].Jesus' avatarian development exceeds that of any once living being. Not the greatest scientists or philosophers of old can be "remembered" in such personal detail. Every aspect of his life has been raked over for centuries to refine the details into someone profoundly memorable. For the true believer, Jesus is as "real" as his mother or ... Bill Clinton.
Jesus can be consulted on any matter, called upon to console ... to encourage ... to forgive ... just as would a living, breathing human being. And ... he has been refined into the perfect logical embodiment of the general female philosophy.
Thus, is it any wonder that anyone who calls into question His very existence would be totally ignored?
