Earth is the only major planet we acknowledge of that has ever had a flaming . While there may be volcanoes press out blistering magma on the airfoil ofVenus , the hot major planet in the Solar System , there has never been a fire there . Nor on Mercury , nor Jupiter , nor any of the other planets surrounding our or any other star .
In fact , for billions of years of the Earth ’s chronicle , there was n’t any flaming either . It deal billions of year before the condition for ardor were possible , with the satellite ’s first inhabitants living in a humans without fire for long than it ’s possible to imagine . While volcanos would have get " fire fountains " like those likely produced on Io – and there may have been the odd flame from a gassyvolcanobelch – this is magma being forced up and sprayed out a vent , rather than real fire .
Around 2.4 billion years ago , the Earth ’s ambience was likely a thick haze of methane , the resolution of bacterial life emerge on the planet . Then theGreat Oxidation Eventhappened , where ancient cyanobacteria began to produce vim from sunlight , releasing atomic number 8 into the atmosphere . Here , molecular O start to accumulate in the atmospheric state for the first time , though still not in enough concentration for combustion to take place . The Great Oxidation Event , sometimes cognize as the Oxygen Catastrophe , likely plunged the Earth into aworldwide deep freezeas this oxygen destabilized methane , clearing it and crumple itsgreenhouse effect . The Earth became cold , as well as fireless .
The first fogey platter we have of flame comes from the Middle Ordovician period , billions of years later . In term of fervor , there is a sweet touch . Any down than13 percentage O , and plant affair will not combust . Any mellow than 35 percent it will throw a fit so well that timber would not be capable to grow and sustain themselves .
In the Ordovician period 470 million twelvemonth ago , the first land plants – mosses and liverworts – make more atomic number 8 , finally creating enough denseness of it to visit fires upon themselves . finally , around 420 million geezerhood ago , we have the first fossil grounds of fire on Earth , charcoalfound in rocks from this full point . However , with oxygen levels still fluctuating wildly , the first all-inclusive wildfires did n’t take place until around383 million geezerhood ago . And flack have been a real jolt ever since .
