But in spite of all that has been done scientifically and otherwise, no one has . Date Event 4540 Ma Planet Earth forms from the accretion disc revolving around the young Sun, perhaps preceded by formation of organic compounds necessary for life in the surrounding protoplanetary disk of cosmic dust. 2. LIFE IS THE RESULT OF . Images are taken from the movie 'The Whole History of the Earth and Life' produced by the Hadean Bioscience Project . Microbial life forms have been discovered on Earth that can survive and even thrive at extremes of high and low temperature and pressure, and in conditions of acidity, salinity, alkalinity, and concentrations of heavy metals that would have been regarded as lethal just a few years ago. Thus, the ability to copy the molecules that encode genetic information is a key step in the origin of life without it, life could not exist. The earliest representative of the genus Homo is Homo habilis, the 'handy man', so named because of his skill at making and using stone tools. These newly formed organisms would evolve into all forms of life on earth today. Modern civilisation begun 10,000 years ago. . Through much of its lifespan, the planet looked vastly different than today. These rocks are rare because subsequent geologic processes have reshaped the surface of our planet, often destroying older rocks while making new ones. All we know for sure is that it happened after Earth formed 4.5 billion years ago, and before 3.4 billion years ago - the time of the oldest . When did human life begin on Earth? According to recent findings, the original Hominids emerged (or arrived) on planet earth between 5 and 7 million years ago in Africa, when a handful of mature apes felt it was high time to begin walking upright. For decades most scientists assumed that life emerged billions of years ago in a "primordial soup" somewhere on the Earth's surface. Human beings were developed on Earth from now extinct primate. Even before Buick's discovery, ample evidence indicated that life on Earth began while our 4.5 billion-year-old planet was very young. Life appears to have been here for a very long time. Its earliest period remained chaotic and semi-apocalyptic for millions of years. on Facebook . Even the theory that life started . (Image credit: Rob Bayer/Shutterstock.com) Earth is estimated to be about 4.5 billion years old, and for much of that. Using the tools of science, we have learned that Earth is about 4.5 billion years old. The earliest known fossils on Earth date from 3.5 billion years ago and there is evidence that biological activity took place even earlier - just at the end of the period of late heavy bombardment. The origins of life are known to have come after the presence of liquid water on earth. Here was a critical period of the evolution of planet earth. Evidence is mounting, however, that life may have begun deep beneath the surface, perhaps near a volcanic ocean vent or even inside the hot crust itself. How did non-living molecules that covered the young Earth combine to form the very first life form? It took 13.8 billion years of cosmic history for the first human beings to arrive, and we did so relatively recently: just 300,000 years ago. When did human life begin? Life on Earth began not with humans, but with meteorites and warm little ponds, according to recent research. That life began somewhere between 3.7 and 4.5 billion years ago as meteorites splashed . They were flaking crude stone . The Beginning Earth was created 4.6 billion years ago after an explosion, some strong winds, and gravity worked together to develop all of Earth's layers.

In 1952, Stanley Miller was working with Harold C. Urey and they designed an experiment to see how complex organic molecules might have formed under the conditions of early Earth. One of the greatest mysteries about life on our planet is when and how it first started. Many scientists feel that life could arise by chance because of an experiment first conducted in 1953. The first traces of life recorded on Earth are thought to be as old as 4.2 billion years, indicating that life may have evolved within 200 million years after the first appearance of liquid water. Many experts believe that life began deep down in the sea, where features called hydrothermal vents spit out. Meteorites have been dated to around 4.5 billion years ago, which presumably marks the formation of the solar system and therefore of our planet. Palaeontologist Sankar Chatterjee claims he has found the answer to how life began on earth. Consider Gerard, a professor of entomology . We know that life began at least 3.5 billion years ago, because that is the age of the oldest rocks with fossil evidence of life on earth. Some might assume that a scientifically-minded person would pick "evolution" and that a religious person would pick "creation.". As conditions became more favourable, more complex organisms began to evolve. We then waited until about 100,000 to 70,000 years ago to walk out of Africa into Asia and later Europe, where Neanderthals lived and eventually became extinct. The fact is, many educated people including a number of scientists question the validity of the theory of evolution. The age-old question, "how did life begin?" has baffled humans for centuries. It is quite clear that what was known more than 100 years ago, even intuitively before that, is that the fusion of sperm and oocyte begins the life of a new individual human being. The timeline of human evolution outlines the major events in the evolutionary lineage of the modern human species, Homo sapiens, throughout the history of life, beginning some 4 billion years ago down to recent evolution within H. sapiens during and since the Last Glacial Period . When life occurs on Earth, as a rule, the age of the Earth is taken into account, which is logical. Christians and Jewsbelieve in the making of man by God on the sixth day of creation (some 4,000 years ago) out of clay and in His own image, as told in the Book of Genesis [see next page].

Trace back far enough, and you're related to the first mammal who lived 220 million years ago. All living things reproduce, copying their genetic material and passing it on to their offspring. Ancient humans began to use prepared core technologies (hand tools made of rocks like flint that were pre-shaped by flaking off small pieces, before larger flakes were removed), marking a change in human culture. As humans, we are members of the Hominidae, which includes great apes, gorillas, chimpanzees, and human beings. Why is the Moon important to life on earth? .

For nearly 4.5 billion years the story of earth goes. The researchers suggest molecules that are normally difficult to manufacture could be grown in droplets, then extracted. Until recently, life on Earth was said to have begun 3.5 billion years ago, a date originally based on curvaceous, worm-like strings of microfossils tiny remains of bacteria, protists, fungi, animals, and plants five-thousandths of a millimetre in length, found in the ancient rocks of Western Australia's Marble Bar. Some of the earliest recorded scientific theories about life's beginning date back to ancient Greece. In an oft quoted letter, written in 1871, Darwin suggested that life arose in a "warm little pond" where a rich brew of organic chemicals, over eons of time, might have given rise to the first simple organisms. 3 billion years of photosynthesis. Some of the oldest evidence of life on Earth is 3.49-billion-year-old fossilised remains of microbial mat structures, which look like wrinkle marks in rocks, found in the Pilbara region of Western Australia. The Scriptures introduce man as a created being. Replicating molecules evolved and began to undergo natural selection.
