"Karman line is the border that separates the Earth's atmosphere from outer space. It is defined as being 100 km above sea level by the Fédération Aéronautique Internationale. This is regarded as the starting point of outer space, i.e. where the atmosphere is too thin to support flight." - u/SunCloud-777
4.
"The first book featuring a ship going into outer space and meeting aliens was written in the 2nd century AD" - u/nasandre
