Are you really tryna justify this shyt or are you just playin devil's advocate.
Yoda and Obi-Wan both knew about the prophecy in the prequels. They both knew about Anakin. There would be no reason for them NOT to allude to it. When Obi-Wan appears to Luke in ROTJ and pretty much confesses everything to him there isn't even the slightest hint about Anakin being anything more than Luke's father.
The biblical and spiritual poetry throughout Star Wars imo was already strong enough (hint hint SKY-WALKER). He didn't have to shove it down everyone's throat and turn Anakin into Jesus Christ by copying his exact origin.
And if Anakin truly was the chosen one then he is the worst chosen one in the history of chosen ones. Dude goes on to basically fukk up the galaxy.
