    Well, outer space is defined as that region more that 75 miles from sea level earth and there have been countless people well beyond that. The first, Alan Shepherd went that high riding a Redstone rocket May 5 1961.

    62.1 miles up is the Karman line.

    The Karman line is pretty well defined at 100 km.  There are various definitions of where our atmosphere ends and outer space begins, some as high as 120 km.

    In 1961, Yuri Gagarin's first human orbit around the Earth varied in altitude between 169 km and 327 km.  That means humans have been going to outer space for nearly 60 years. 

    The International Space Station orbits at around 400 km.  That means there were humans in outer space continuously for a span of nearly 20 years.

    Plenty of people have been above the Karman Line.

    No, that is NOT true. The Karmen line is at 100 kilometers or 61.7 miles.

    If you really mean where does the exosphere end, that is a lot more indefinite, up to 10,000 kilometers. The height of the Earth's atmosphere varies a lot. 

    If you mean the Hill or Roche sphere of the Moon, that would be true. 

    "Outer" does NOT mean outside of the Solar System traditionally. "Interstellar" means outside of the Solar System.

    The phrase 'outer space' rarely has any precise definition.

    At present, it would be logical to call space flight beyond Earth orbit to qualify as such.

    The definition of the word "outer" makes that true, because it usually is taken to mean "outside the solar system."
