Let's discuss the Timelord, timeline. Assuming Timelords are an individual species where do they originate? If they so closely resemble humans, and as Matt Smith's doctor said, "No, you look Timelord." If we take this statement as a deeper sign of the world, and that the doctor's arrogance is very similar to that of which an Immortal Human being would have, lets go down a little rabit hole of Where the crap did Timelord's come from? So the Gallifrayans look like hairless apes, only with some new cool toys. Using the Timelords referenced in the Eccelston and forward period, we can inference that, while possessing a few adaptions(additional heart, regeneration, expanded memory) all could be plausible in a human evolutionary timeline, this will lead to some fun ideas. The Doctor himself is OBSESSED with humanity? Why? Is it love of history? Or could it be that the Doctor just wants to preserve a species? Highly unlikely, I think it more plausible, that he's preserving the creation of his people. Why? If Timelords' are a progression of human evolution(Like I'd like to believe) then lets start with assumptions, what factors could make humans that awesome? Step One: We invent timetravel. Step Two: We abuse Timetravel, so that we as a species reach every scientific advancement EARLIER. Step Three: Rinse, Repeat. Until we as a species don't have a dark age, or any period of regression, and not only do we not ever not move forward. We move forward faster then we can fathom, leap frogging our species through billions of years of advancement, and creating an enormously different species timeline, earth itself could even become gallifray, It supports life, and was named by a species created by humanity. That would not really be human, because human is our factual history, and this would be a massive condensate of our species history, which assuming that the humans time traveling only view as marginally important, as opposed to the scientific leaps and bounds that led us to time travel, then even if we're handing off complete histories, they'll be largely ignored in favor of the hard facts of the science that led us to time travel. So immediately following our species reaching cognition(formal thought, and the only real thing that separates from the beasts of instinct) would have the information needed to leap them into time travel, then there wouldn't be a 'human' history, and would create the paralell, yet identical species of the timelords. Any questions?
It seems to me that billions of years before earth, humans lived on Gallifrey aswell and become timelords through years of exposure to the untampered schism. So the doctor is so obsessed with humans as his race used to be humans themselves
