We think the first person on the moon looked like in our Astronaut on the Moon Sticker. The first man to set foot on the moon was Neil Armstrong, an American astronaut who was part of the Apollo 11 mission. Armstrong famously declared - that's one small step for man, one giant leap for mankind. He became the first person to step onto the lunar surface. The Apollo 11 mission marked a significant milestone in human history and solidified the United States' dominance in the Cold War-era space race against the Soviet Union.
