Who became the first man to walk on the moon?

Neil Armstrong became the first man to walk on the moon on July 20, 1969, during NASA's Apollo 11 mission. As the mission commander, he famously took his first step onto the lunar surface and stated the memorable words, "That's one small step for man, one giant leap for mankind." This historic event marked a significant achievement in space exploration and represented a culmination of efforts in the Space Race between the United States and the Soviet Union.

While Buzz Aldrin was the second person to walk on the moon shortly after Armstrong, Yuri Gagarin was the first human in space, orbiting the Earth in 1961, and John Glenn, a pioneer in American spaceflight, was the first American to orbit the Earth. Their contributions to space exploration are monumental, but none achieved the milestone of walking on the moon prior to Armstrong.
