Aerobic,carbon units,have shared surface of earth "only" 500 millions of years!Anaerobic life forms had appeared before 3.5 billion years.Were there "non oxygen" civilizations on Earth's surface? http://www.dorak.info/evolution/life.html - http://www.dorak.info/evolution/life.html http://encyclopedia2.thefreedictionary.com/Loricifera - http://encyclopedia2.thefreedictionary.com/Loricifera |

I think they exsist on Europa.....good stuff . ------------- "Absence of evidence is not evidence of absence" S. T. Friedman Pilger's law: 'If it's been officially denied, then it's probably true' |

It is 20 lightyears away so until we can travel at the speed of light, we will never set foot there. Yet it happens to have sufficient water to harbour life and is even suspected to contain oceans. It's surface temperature is also similar to earth. It lacks oxygen but we can at least assume that some form of bacteria or unicellular organisms have evolved in there. Technically speaking, I believe that it is possible for those anaerobic organisms to have evolved into something more complex, the same way cyanobacteria and plant protists evolved into plants. Why do these slightly habitable planets always happen to be so far away? maybe for our own safety, perhaps? ------------- Timidi mater non flet |

Researchers have in many occasions stumbled across meteorites containing low amount of amino acids. Amino acids are the building block for proteins and as anyone interested in biochemistry would know, no life can exist without proteins because they are what makes up many cellular organelles, enzymes, carriers and cytoskeleton...etc. They found glycine which happens to be the simplest amino acid with a hydrogen side chain. Regardless of that fact, any amino acid needs a ribosome to synthesize it, ribosomes require DNA to operate and DNA would have to come from a cellular organism. This technically proves that there is live out there.

CV and Baal,I am talking about Earth's past also!Why do we avoid that!?3.5/3.7 billion years have been hell a lot of time,Earth would have been empty?No screenplay,No drama and screenplay writers?  Do we needanaerobic history books of Earth's history?  |

| This gives chances to Venus,Mercury,Jupiter,Saturn for life evolution also!Our Earth had spent 3.5 billion years without oxygen.But energy have always existed here,inside the Earth and from the Sun!Where are now traces from those civilizations,had developed during those 3.5 billions of years? |
