Yuri Gagarin did.
Gagarin made one orbit of the earth in 108 minutes before coming back home.
Gagarin was the first person to leave the Earth's atmosphere.
Yuri Gagarin orbited the Earth once during his historic space flight on April 12, 1961. He completed one full orbit before safely landing back on Earth.
Yuri Gagarin's first flight was to space. On April 12, 1961, he became the first human to journey into outer space aboard the Vostok 1 spacecraft. Gagarin's historic flight lasted 108 minutes, orbiting the Earth once before returning safely.
Yuri Gagarin became the first person into outer space on the 12th of April, 1961.
He wasn't. Yuri Gagarin orbited the earth - once - in 1961, a year before Glenn's flight.
No human being has ever flown into Orbit before Yuri did. The soviets only flew their sattelites and put them into Earth's orbit. So we can indicate that: Yuri Gagarin is the first human being sent into Space :)
