Question

Why did Dr. Who choose some inferior human as an assistant?

Answer 1

Make himself look good?

Answer 2

If he choose someone superior then he would be the assistant.

Try not to think too hard about it, its a bit like asking  why aliens always attack America in Hollywood movies?

Answer 3

Have you ever watched the classic series?  Doctor Who has had companions from other worlds, and one of his companions was a robot.

Romana, who was one of the companions during the Tom Baker years, was a female Time Lord and consequently very much the Doctor's equal.

As for why he chooses humans:  The Time Lords were destroyed in the Time War against the Daleks, so there are no more Time Lords to travel with him.  The Doctor loves the Earth, and he does love humans even when he gets on a tear and calls us things like "semi-evolved apes" and other such.  With a human, who still thinks that only our planet is inhabited, he can not only teach them about the universe and show them the universe, but he can also experience their wonder and their joy and seeing all these new planets and species for the first time.

Besides, why wouldn't he choose a human?  The Doctor is just cool like that.

Answer 4

because he's got Two big harts.

boom boom.

Answer 5

The reason the Doctor has so many human companions is because the production team and writers (and I mean most, if not all of them since 1963) have always felt that the viewer needs somebody to relate to. Somebody that can ask the Doctor the questions that need to be asked so that the Doctor can explain what's going on to the viewer. It's as simple as that. It was illustrated quite well in the episode "Partners in Crime", when the Doctor started explaining something, but then stopped mid-sentence, because he realised he was alone in the Tardis. So the viewers never found out what he was going to say.

As bookshop_lady has said, the Doctor has had quite a few non-human companions in the past, Including fellow Time Lords (Romana and Susan), as well as robots and human scientists who were closer to his intellectual level.

The various production teams and writers over the years, were never entirely happy with those companions, however, since there was always a lot of stuff they didn't need explained to them, where as an ordinary person would have needed an explanation. So it was a lot more difficult for the writers to inform the viewers about some aspects of the plot.

Answer 6

He has a fondness for Earth and lets face it, he wouldn't get much chemistry or conversation out of a sheep now would he?

He also has a fondness for humans, has stated in several conversations with human-killing aliens, that he sees their potential (well, it is fiction), and so he likes the company of humans.
