The whole thing about Anakin's parentage is so stupid, illogical, and convoluted, nevermind that it's incredibly underdeveloped for what is [if true] a central pillar of a six-movie series. If Palpatine is the father of Anakin and the grandfather of Luke, and the mastermind of every single event across six movies, then that definitely deserves more mention than a single line that was simultaneously focused on a separate matter [Anakin's desire to keep Padme from dying].
Never mind that this power is never once mentioned anywhere else across six movies. It's not suggested, it's not hinted at, it's not mentioned, it's not explicitly stated. We all know by know that George Lucas [and Star Wars] doesn't have an ounce of subtlety. Nor is this power ever explicitly shown even a single time in six movies. We never see the power being used to create life, we never even see it being used to
save someone's life. The only reason we know the power exists is because it was told to us [and Anakin] by a master manipulator whose whole stick is to lie and deceive everyone he comes into contact with. For all we know, that whole thing was another Palpatine lie to bring Anakin further under his control and that Anakin actually had a really ordinary father that his mother didn't want to talk about. And please don't bring the Expanded Universe into this.
For whatever reason - I'm going to guess on the advice of others - he either didn't film or edited out the scene he wrote in which Sidious directly confesses to Anakin that he made him.
This idea is hopelessly absurd. We know by now that the contents of the PT were fully under the control of Lucas and nothing happened that he didn't sign off on. Who, exactly, convinced him not to use that scene? Who stepped forward, for the one and only time, to say "No." to the billionaire who created this franchise, owns it completely and utterly, who produce/directed/wrote this turkey and owns the production company and special effects house? No one, because that person doesn't exist. If he wanted that scene in there, it'd be in there, and I honestly can't think of a single person who could have convinced him to cut it [maybe Spielberg lol], not in light of all the incredibly awful stuff that Lucas pushed through across three movies.
