That convinced you, huh? Wow... isn't that taking gullibility to an extreme?
OK... you've got these guys, see... scam artists... near the end of the 1st century, up until the middle of the 2nd century. They've discovered that they're onto a hot scam, with this 'salvation' stuff, because with the Roman occupation going on, everybody was in the mood for a little bit of hope and salvation.
Anyway... this scam required that they create the illusion that a bunch of the mythical stuff in the Pentateuch was coming true. So... they go through the Pentateuch, looking for prophetic sounding stuff... and they make a list. Then... as they create their fictional 'gospel' fantasies', using the VERY well-known 'suffering-hero-king' archetypal pattern, they 'Judaize' it by slipping in a few miracles and some situations that create the ILLUSION of prophecies fulfilled.
The reason the Psalm matches the gospel so well is because when they made this stuff up, they had the Psalm open on the table in front of them, and made sure that they incorporated as many elements of it as they could, without screwing-up the narrative.
Hallelujah... it's a miracle!
Gimme a break.
You really ought to try to learn a little bit about critical thinking... do you know what that is? Anyway... part of that includes the ability to discern what qualifies as actual evidence from what does NOT qualify as actual evidence.
I guess you must have been absent that day.
