Hydrogen and Helium are lost into space'.... I don't think so
"The average speed of hydrogen molecules and helium atoms is greater than the escape velocity from the Earth, and these light gases were lost and swept away through photoevaporation by the solar wind early in the Hadean Eon due to Earth's weak gravity."
Evolution of the Earth's Atmosphere
The atmosphere has too little helium to be able to extract it commercially. "Helium is one of these very limited resources that once you’ve used it, you can never recycle it,"
The best sources are found trapped in rocks after the natural decay of Uranium and Thorium.
