who is the most powerful person on earth?

Yes, at present the President of USA.

Powerful person in the world is the person who pour his powerful light, (I mean his good deeds) to the darker side of the world where no power or lights (I mean the starving and the poor people). Otherwise there's no use of power. He cannot claim he's a powerful person in the earth, because he misused his powerful power without the help to the needy.

yeah...i have to go with the president of US....

i also think that george bush is the most powerful person on earth. the united states is the most powerful country and the president is the most powerful person in the united states, making george bush the most powerful man in the world

I think Bill Gates is the most powerful person in the computer industry and the youngest self-made billionaire in history.

everybody hate him so much.. he use his soldier to kill many people.. and his soldier get killed too

I think no one

Bush

I agree, i think Bush is the most powerful person on earth...

It has to be the Pres. of the USA. Hands down.
