It’s one thing to say the individual who would one day become the Doctor had previous lives. It’s a whole other to say they were going around already fully formed as the Doctor with the police box and everything long before Hartnell.
100% agree! Personally, I would have preferred it if the Doctor was still a regular Timelord but the High Council had given him previous lives before Hartnell (and this would be before he called himself the Doctor). But given the way things are, I’d stick with my crazy idea of killing off the Doctor at Capaldi and having the Valeyard replace him as a “redeemed” figure.
