(Not: I started watching from the ninth Doctor.)
So, I don’t know where exactly to write this so I am going to write it here:
What if the Doctor and the Timelords are actually humans?
Think about it, they look like us and the Doctor said we have gone to the end of the universe, tell me it is not possible to come across a planet called Gallifrey.
This is what I think happened: So people do what people do, colonising the universe and we come across a planet we name Gallifrey. The setlers devote to science so they need more oxygen to their brains, that is why they develop 2 harts over time.There is a time vortex(I am not really sure what was it called, the thing every Timelord had to look at) which inspires them to do stuff about time travels so they menage to create time machines. The problem is they grow old and die so they can’t travel for too long so they invent nanobots that will go through their body and if they get too old or mortally wounded they activate and changer their whole body so they can continue living. They are connected to the time traveling space ships where they get power because they have unlimited energy. That’s why in ‘The Doctors Wife’ they can know the past and the future at the same time, they are like hive mind. So that is why Doctor is concerned about Earth, he is ensuring his survival and the survival of the Timelords.
