Until now, I have found the following scholars about the invention of John the Baptist:
All these theses have their points of force and weakness.
I don't see an argument against the historicity of John the Baptist based on the ethymology of his name (remember that John means
"YHWH gives grace"). Since none has made that argument before now, then
I will make it.
The core of my argument is based on Mark 1:7-8:
And this was his message: “After me comes the one more powerful than I, the straps of whose sandals I am not worthy to stoop down and untie. I baptize you with water, but he will baptize you with the Holy Spirit.”
John was really giving the grace, by his baptism "with water". There is too much "divine coincidence", here, between the name and the action of "John the Baptist".
If you deny that Ebion existed, insofar he founded the party of the "poor ones", then accordingly you have to deny that John the Baptist existed, insofar he gave the grace by his baptism "
with water".
I share the doubts of
Nicholas PL Allen:
One of the tempting conclusions to be drawn from this investigation at this early stage is that given the paltry historical evidence, there seems to be even less reason to believe that someone called John the Baptist existed than say Jesus of Nazareth

In particular, I quote and subscribe fully the following Allen's wonder about Robert Price's "faith" in a historical John the Baptist:
Now, Meager, (1983: 37 - 38), who is also a Christian scholar, tries to rectify the situation by suggesting that Josephus could have drawn from the general knowledge of a Baptist cult in his own day. For some strange reason, R.M. Price seems to buy into this doubtful suggestion that such a cult actually existed.
(my bold)
I don't think that Simon Magus existed, even if Simonians existed. Hence, the existence of a John cult cannot prove the historical existence of John the Baptist.
