Who is more famous Barack Obama or Bob Marley?

Answer 1

It is never easy to answer questions like this, because you are asking us to compare two very different categories of people: someone who is (or was) a musical performer and someone who is a US president. In the case of Bob Marley, he had many fans when he lived, but his music was not as popular as that of, let's say, Michael Jackson; Bob Marley was a superstar of reggae, but that music is still only popular with certain niche audiences, so he would not be as much of a celebrity as some other pop stars of his era.

That said, as much as his fans still miss him, Bob Marley is probably not nearly as well-known or famous as President Obama. The reason is this: not only is Mr. Obama the first black president of the United States, but also, most US presidents tend to be internationally famous, since their policies affect not just the US but the world community. This does not mean everyone likes or agrees with Mr. Obama, but it does mean that more people have heard of him than have heard of Bob Marley.
