The earliest life forms we know of were microscopic organisms (microbes) that left signals of their presence in rocks about 3.7 billion years old. The signals consisted of a type of carbon molecule that is produced by living things.

What is the first form of life existed on Earth?
Prokaryotes were the earliest life forms, simple creatures that fed on carbon compounds that were accumulating in Earth's early oceans. Slowly, other organisms evolved that used the Sun's energy, along with compounds such as sulfides, to generate their own energy.
How was the first life form created?
How did non-living molecules that covered the young Earth combine to form the very first life form? ... Many scientists believe that RNA, or something similar to RNA, was the first molecule on Earth to self-replicate and begin the process of evolution that led to more advanced forms of life, including human beings.
When did humans start on Earth?
On the biggest steps in early human evolution scientists are in agreement. The first human ancestors appeared between five million and seven million years ago, probably when some apelike creatures in Africa began to walk habitually on two legs. They were flaking crude stone tools by 2.5 million years ago.
How was life created on Earth?
It seems possible that the origin of life on the Earth's surface could have been first prevented by an enormous flux of impacting comets and asteroids, then a much less intense rain of comets may have deposited the very materials that allowed life to form some 3.5 - 3.8 billion years ago.
Who created universe?
Many religious persons, including many scientists, hold that God created the universe and the various processes driving physical and biological evolution and that these processes then resulted in the creation of galaxies, our solar system, and life on Earth.
Who made humans?
Modern humans originated in Africa within the past 200,000 years and evolved from their most likely recent common ancestor, Homo erectus, which means 'upright man' in Latin. Homo erectus is an extinct species of human that lived between 1.9 million and 135,000 years ago.
What color was the first human?
These early humans probably had pale skin, much like humans' closest living relative, the chimpanzee, which is white under its fur. Around 1.2 million to 1.8 million years ago, early Homo sapiens evolved dark skin.
Where do the first humans come from?
Humans first evolved in Africa, and much of human evolution occurred on that continent. The fossils of early humans who lived between 6 and 2 million years ago come entirely from Africa. Most scientists currently recognize some 15 to 20 different species of early humans.
How did time start?
According to the general theory of relativity, space, or the universe, emerged in the Big Bang some 13.7 billion years ago. ... "In the theory of relativity, the concept of time begins with the Big Bang the same way as parallels of latitude begin at the North Pole.
Which God made the world?
In the first, Elohim (the Hebrew generic word for God) creates the heavens and the Earth, the animals, and mankind in six days, then rests on, blesses and sanctifies the seventh (i.e. the Biblical Sabbath).
How did the world begin?
Earth formed around 4.54 billion years ago, approximately one-third the age of the universe, by accretion from the solar nebula. Volcanic outgassing probably created the primordial atmosphere and then the ocean, but the early atmosphere contained almost no oxygen.
Who were the first people on earth?
Homo sapiens, the first modern humans, evolved from their early hominid predecessors between 200,000 and 300,000 years ago. They developed a capacity for language about 50,000 years ago.
When did Adam Eve live?
They used these variations to create a more reliable molecular clock and found that Adam lived between 120,000 and 156,000 years ago. A comparable analysis of the same men's mtDNA sequences suggested that Eve lived between 99,000 and 148,000 years ago1.
What was the first race?
In 1895 the first true race was held, from Paris to Bordeaux, France, and back, a distance of 1,178 km. The winner made an average speed of 24.15 kph. Organized automobile racing began in the United States with an 87-km race from Chicago to Evanston, Illinois, and back on Thanksgiving Day in 1895.
What Colour is human skin?
Human skin color can range from almost black to nearly colorless (appearing pinkish white due to the blood in the skin) in different people. In general, people with ancestors from sunny regions have darker skin than people with ancestors from regions with less sunlight.
Where was the first man found?
Most have been found in Eastern Africa. In 2003 a skull dug up near a village in Eastern Ethiopia was dated back to some 160,000 years ago. Its anatomical features — a relatively large brain, thin-walled skull and flat forehead — made it the oldest modern human ever discovered.
