[quote:Anonymous Coward 31812044:MV8yMTA2Mjg1XzM1NTAwNjI1XzVFOUNGQTFD] Guys before you shit yourselves. The article probably means free oxygen. Ie oxygen gas floating about. The oxygen would have been present, just not in gas form. Pure water is 33% oxygen for example, thats without oxygen gas being dissolved in it. All the oxygen gas we have today was probably liberated from compounds by the likes of ancient photosynthetic micro-organisms. [/quote]

Researchers have found fossils of bacteria that a nearly 3.5 billion years old, believed to be the oldest visible fossils ever uncovered. The fossils, found in northwest Australia's Pilbara region, are from a time before oxygen existed on Earth and are from just one billion years after Earth's formation, according to Old Dominion University's Nora Noffke, one of the researchers who worked on the project.
