I am afraid i am most confused as i seem to have been brought to the future by a man named John Titor. Anyhow, he brought me here to answer your question. Answer - Many bacteria and indeed other microorganisms are capable of metabolic processes without using oxygen, these are known as anerobic. You will find they are quite common, and should be referenced in any high school textbook. Good day sir! Hi there Dazza nice to see you. To continue with this theme, The first forms of life on Earth are speculated to be hyperthermophilic anaerobic bacteria which respire without oxygen and live at very high temperatures ----> environments like volcanic thermal springs. |

Quoting: Anonymous Coward 31810416 Please don't say Carbon 14. Anyway, if life existed on Earth before Oxygen, wouldn't that mean that the "primordial soup" is disproven? That would suggest that life did not indeed come forth from the "primordial soup" but from another source instead. c14 is not even possible on baterial life |

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. I do not believe they did not used carbon dating, so I'm sorry but I will have to raise our flag. Because of this: Thread: CARBON DATING IS BS - DECAY RATES RANDOM |

For radiocarbon dating to be possible, the material must once have been part of a living organism. This means that things like stone, metal and pottery cannot usually be directly dated by this means unless there is some organic material embedded or left as a residue. As explained below, the radiocarbon date tells us when the organism was alive (not when the material was used). This fact should always be remembered when using radiocarbon dates. The dating process is always designed to try to extract the carbon from a sample which is most representative of the original organism. |

Another dating method is using Magnetostratigraphy [link to en.wikipedia.org] in which again, it is the rock in which the sample is found that is dated. |
