I'm not questioning the historicity of anybody. I'm saying that all of your reasons to doubt the reality behind the Jesus of the gospels could equally be said about many other characters from history.
You said in your OP that your thoughts are 'Based on the limited research I've conducted over the past few days'. I agree it is an interesting topic but I think you should dig a lot deeper.
The best case for a historical Jesus is probably made by Bart Ehrman. The best and most recent case for a mythical Jesus is made by Richard Carrier.
