helium is a noble gas and is found in the earth's atmosphere and not in the oceans nor in the earth's crust
Sunlight.
Earths oceans gain water considering evaporation and precipitation together since when vapour is released to the atmosphere it condenses and later falls back as rainfall by about (1-5)%
hydrogen
because helium is toxic for most living things for that reason its rare to find but that's why its mainly used for balloons n more for ex:filling party balloons as it is a much safer gas (non-flammable)widely used as an inert gas shield for arc weldinghigh speed push gas inside air to air missiles for guidence corrections.protective gas in growing silicon and germanium crystals, and in titanium and zirconium productioncooling medium for nuclear reactors, helium won't become radioactivea mixture of 80% helium and 20% oxygen is used as an artificial atmosphere for divers and others working under pressurecryogenics and superconductivityrare document preservation (i.e. Declaration of Independence)as a gas for supersonic wind tunnelspressurizing agent for liquid fuel rockets (inert so won't react)leak detection agent for extremely small leaks.nuclear detonation simulations (using conventional explosives)isotopic dating by helium ratios (seawater, ocean beds,etc)helium/neon lasershelium cardio-pulmonary resusitation pump (heart surgery)helium filled border patrol "AEROSTAT" monitoring blimps

A the answer is hydrogen

The free oxygen bubbled up from the oceans.
