[Doctor Who] Why did the doctor de age and basically become space Jesus when everyone in the world said his name at the same time?

Because the Archangel Network, a ton of extraterrestrial Time Lord satellites The Master constructed, were merged with the minds of every human on the planet. All of them directing their networked minds toward one person allowed him to use the combined psychic ability of *billions* of people.

Psychics and psychic abilities, latent or otherwise, are canon in the whoniverse, and a good hundred people who aren't outwardly psychic have the abilities of one together. So multiply that by how *many* hundreds of people he's actually harnessing, and it makes sense that he can easily reshape flesh and use telekinesis.
