These 3 lines may be more cause for speculation than many others in recent Star Wars especially Obi-Wans statement that Luke in The Chosen One but well break that down in another piece.
Why does obi wan say luke is the chosen one. This screenshot is for warcraft 3 players. He doesnt he just deduced Obi-Wan was on Tatooine protecting someone and asked if the someone was the Chosen One as he died. We all know its Anakin Filoni says firmly.
No my father didnt fight in the wars. It was a tactic they felt was necessary because theyd both made the. As is shown in ROTS they were BOTH intended to be trained as Jedi and the timing of the training was pretty much left by Yoda to the Force.
The bitterness and disbelief he expressed at that moment spoke volumes about his state of mind. The only thing I can think of was that he wanted to inspire Luke by saying his father wanted him to have it to increase the chances he would agree to come with Obi-Wan. He was a navigator on a spice freighter.
We know Obi-Wan stretched the truth but come on there was no reason to lie about it. To this end he might have considered it better to Bend the truth a little and tell Luke that Darth Vader killed his father rather than that Darth Vader was his father. Part of its appeal beyond lightsabers and space ships was the character of the quotable old Jedi Master known as Obi-Wan Kenobi.
Even ignoring the fact that it wasnt written yet Obi-Wan still has a good reason. Obi-Wan eventually doubles down on his commitment to Luke by making the ultimate sacrifice. However a reasonable explanation is that Obi-Wan lied about it as a recruiting technique.
Luke wasnt chosen - he just happened to be the first to get around to you know train to become one. Jedi and Sith commonly believed that the Force determines everyones lives and I feel that Kenobi was chosen to somehow endure and suffer throughout his whole life while trying to adhere to a Jedi code he starte. And Obi wasnt concieved by the Force like Ani and he dosent have vissions of the future.
