  1. Water on Earth! Derived from 75% of the hydrogen element in the universe! Because the earth is in the orbit of the universe, Gravity of Earth will catch a lot of hydrogen! At this point, the unique element oxygen on Earth will combine with these hydrogen elements to form water! Put it another way! If you're looking for aliens! We need to find planets with oxygen!
