An amateur can see through the fallacious arguments that a lot of these so called scholars present.
You've never read the arguments, so you have no idea.
Additionally, your arguments are completely specious. You have to posit the most improbable situations to get the results you do, such as:
1. Although Paul uses a standard kin formula only for James, and calls James Jesus' brother, he wasn't actually Jesus' brother.
2. Although the reference to James, Jesus' brother, in Josephus, is completely UN-christian, you suppose it to be a christian interpolation, although no Josephan scholar does
3. Despite the fact that NO myth from the ancient world was based around a figure living WITHIN a lifetime of the myth's composition (i.e. Mark) and the gospels have numerous time been compared to graeco-roman biography, you imagine that Mark is pure fiction.
4. Despite all research from the sociology of religions tell us that cults, such as the Jesus sect, not not build around mythic founders, you believe the Jesus sect did.
5. Although Luke, Paul, and John all knew disciples of Jesus, you discount everything they say as pure fiction, despite the fact that there was no such genre in the ancient world.
6. Although more information was written about Jesus very close to his mission than with virtually ANY other figure from history, and there is NO evidence, even from critics of christianity, that Jesus nevert lived, you ignore all of this.
And so forth.
There is a reason that 200+ years of critical research keeps coming back with the same answer: at the very least, Jesus was a historical first century Jew, who had followers, taught, and was executed.
