EARLIEST EVIDENCE OF LIFE2IntroductionThe origin of life has been a very critical and divisive question in the minds of almost all the beings present in the world. Initially, religion filled the void by allocating this magnificent powerto a supernatural body. With emergent of scientific research together with archeology, several theories are streaming in. their effect is building more confusion among the population while on the other hand triggering an intensive research into the topic. So far, the formation of the earth aswell as other evenly bodies have been attributed to the big bang theory together with other theories. As much we may not all agree on the very exact method on which the world was formed the scientific research and archeological activities so far is enough to convince the entire population that life was present on the earth’s surface a billion years ago [ CITATION Bax14 \l 2057 ]. The form upon which life existed at that time is also certain to be different to what we currently have considering several extinction phases that have been seen on the earth’s surface across the years. Now the question of contention is the original source of this life as well as the transformation procedure which oversaw the changes in the forms of life within the years[ CITATION Oht14 \l 2057 ].Earliest Evidence for LifeA research on the ancient presence of life on the planet earth is majorly fronted by the archeological analysis of fossil evidence. The earth is approximated to have been formed 4.54 billion years ago. Scientists conventionally agree with findings suggesting life existed on earth 3500 million years ago though there are signs that life might have been present even before the suggested dates. In 2017 scientists tabled the discovery of microfossils in the hydrothermal vent precipitate within Nuvvuagittud Belt found in Quebec Canada. The fossils of organisms are in the form of tiny filaments knobs and tubes in the rocks of Canada. These are believed to be signs

EARLIEST EVIDENCE OF LIFE3of the existence of life in the ancient times. They are claimed to have been there some 4280 million years old. Based on this date these organisms existed just a brief time after the formation of the planet and several years prior to what is currently considered as proof of the presence of life in the ancient years [ CITATION Alt09 \l 2057 ].The putative microbes discovered from Quebec are a tenth of the width if compared to the size ofa human hair and have elements of haematite in them. The structure of the fossil is enclosed in quartz layers within the Nuvvuagittuq Supracrustal Belt abbreviated as NSB. The NSB is a portion of the very old ocean floor with sedimentary and volcanic rocks present in it. Archaeologies have attested to this. Currently, the most ancient acknowledgement of life being present on earth is contained in the old rocks located in Western Australia. They are dated to 3.48 billion years. The rocks indicate remnants of stromatolites [ CITATION Pal17 \l 2057 ].The fact that previous evidence indicated that microbial life on earth’s surface come from 2700 to 2900 million-year-old deposits discovered in South Africa soils rich in the organic matter means there is proof that life was present in the land by over 500 million years. These are signs that life developed in the freshwater hot springs inland rather than the idea that life fast began in deep sea before later adapting to land [ CITATION Tar17 \l 2057 ].Form of earliest Evidence for LifeThe discovery of a biogenetic graphite is one of the ancient proof of the existence of life on the earth’s surface long time ago. This graphite was approximated to be 3700 million years old. Then the discovery of metasedimentary rocks the west of Greenland together with
