Which Apollo mission landed the first humans on the Moon?

Apollo 11 became the first spaceflight to take humans to the Moon and land there. Well-known astronauts, Neil Armstrong and Buzz Aldrin, landed on the surface of our natural satellite the 20th of July, 1969. Approximately six-and-a-half hours later Neil became the first human to ever walk on the Moon. His partner followed him as well. Together with Aldrin they collected enough lunar material for the further research at home. They spent more than 2 hours working outside the spacecraft. The success of this mission became not only one of the most significant events of the epoch, but an important and memorable moment of the entire history of humanity.
