Summary

• Obi-Wan's choice to take Luke to Tatooine demonstrated his belief that Luke was destined to fulfill the Chosen One prophecy.
• Despite learning that Anakin was still alive, Obi-Wan maintained his belief that Luke was the Chosen One.
• Obi-Wan believed that Luke would succeed where Anakin failed, and he had faith in Luke's ability to bring balance to the Force.

Obi-Wan Kenobi took Luke Skywalker to live on Tatooine with his family in Star Wars, and while it may seem like a strange choice at first glance, it demonstrates that Obi-Wan thought Luke was destined to fulfill the Chosen One prophecy. Obi-Wan didn't learn that Anakin had survived their duel on Mustafar until 10 years after Star Wars: Episode III - Revenge of the Sith, leading him to assume that Luke was the next logical choice.
However, Obi-Wan still believed that Luke was the Chosen One even after learning that Anakin was still alive. This is evident in Obi-Wan's words and actions, illustrating how he always had this faith in Luke. Hiding Luke on Tatooine was the first indication, as it set Luke on a drastically different path from his father's.
