Yes ...re, in fact ...
Well it's not perhaps, is it? But OK.Perhaps I stand corrected and that is fine.
The point being, your claim:However, none of this renders proof of the objective existence of The Son of God: Yeshua. If anything it demonstrates how Mankind is capable of inventing its heroes and villains.
"Posthumous writing means nothing only text that was actually authored by Yeshua would count as HIs philosophy."
Is nonsense. Scholarship clearly refutes you.
"However, none of this renders proof of the objective existence of The Son of God"
Not to your satisfaction, perhaps. Again, scholars largely agree that a person existed, and was crucified.
"If anything it demonstrates how Mankind is capable of inventing its heroes and villains."
Sorry, but that argument rest on a logic fallacy.
Because some historical figures without your 'proof' are fictions – Socrates, Phthagoras, Robin Hood, Bigfoot, etc. – that does not mean that all figures without such 'proof' are therefore fictions.
