europa, oxygen, more water than earth's

lakotahope says:

Now one has to figure where it comes from on Europa? We know where our oxygen sprang from--minuscule ocean critters (scientific name), and plant life. This planet didn't start off with an oxygen atmosphere....some conclude a chemical reaction took place to release it from the primal waters...can't remember exactly.

I'm just wondering how in the world they even came to that conclusion...
