Who are alive today?

Answer 1

Judaism believes that the age of prophets ended centuries before the time of Jesus. Most Christians accepts that view.
Islam believes that Muhammad was the last and final prophet.

Mormonism believes that its founder, Joseph Smith, was a prophet, as are the presidents of the Church and all others who have "the testimony of Jesus Christ, for that is the spirit of prophecy." Thomas S. Monson is the current president and therefore, in Mormon belief, a prophet.
