Scientific evidence suggests that life began on Earth approximately 3.5 billion years ago. The Earth formed 4.5 billion Years ago.
The Earth was a dead planet for about 1 billion years.
Some evidence would suggest that the first forms of life began more like 3.8 billion years ago, in which case the Earth was dead only 700 million years.
The study of the processes which resulted in the beginning of life is called Abiogenesis.
If it worked the same on other planets on other Sun in other galaxies, life may have begin 10 billion years ago in other galaxies.

Note also that there are dozens of explanations for the beginning on life on Earth, including many based on religion.
Life on Earth began to evolve around 3.5 billion years ago, with the earliest forms of life being simple single-celled organisms. Over time, these organisms diversified and evolved into more complex life forms, eventually leading to the diversity of life we see on Earth today.

How much time have organisms had to change?
Organisms have had approximately 3.5 billion years to evolve and change since the emergence of life on Earth. This long period of time has allowed for the incredible diversity and complexity of life we see today.
What role did cyanbacteria play in the evolution of life on earth?
Cyanobacteria played a crucial role in the evolution of life on Earth by being one of the first organisms to perform photosynthesis, releasing oxygen as a byproduct. This helped to transform the Earth's atmosphere, making it more hospitable for other life forms to evolve. Cyanobacteria are also believed to be the ancestors of chloroplasts in plant cells.
Why do scientists think that photosynthetic prokaryotes were not the first life forms on Earth?
Scientists suggest that photosynthetic prokaryotes were not the first life forms on Earth because the conditions on early Earth were likely not conducive to sustaining photosynthesis. It is believed that simpler forms of life, such as chemotrophic prokaryotes, which obtain energy through chemical reactions, may have been the first life forms to evolve. Over time, photosynthetic prokaryotes evolved as the environment changed and oxygen started accumulating in the atmosphere.
What was the first type of true cells to form on earth was?
Prokaryotic cells were the first type of true cells to form on Earth. These cells lacked a defined nucleus and other membrane-bound organelles, but were able to carry out essential functions of life.
What affects have mass extinctions had on the history of life?
Mass extinctions have had a profound impact on the history of life by dramatically altering the diversity and composition of species. They have caused major shifts in ecosystems and have created opportunities for new species to evolve and adapt. Additionally, mass extinctions have played a key role in shaping the evolutionary trajectory of life on Earth.
Why has life become possible only on the Earth?
Life formed on earth because the conditions were right for life to begin and evolve. While some think that life (as we know it) is only possible on our earth, others think that somewhere, in the vastness of the Universe, life on a similar planet to earth must exist.
Where did life on earth evolve from?
Probably photosynthetic multicellular protists, such as Rhodophyta and Chlorophyta.
When did the biosphere begin to evolve?
The biosphere is defined as the living organisms on earth. As such, it began to evolve when the first organisms appeared. Currently, this is believed to have happened about 3.5 billion years ago.
Where did homosexuality begin?
Homosexuality began wherever life on Earth began.Homosexuality began with the dawn of animal life on Earth.
When did the earliest life evolve?
The first life apeared on earth some time around 4.4 billion years ago.
When did life first begin?
There is evidence of life on Earth since around 3.7 billion years ago.
When does a whirlipede evolve?
Whirlipede will begin to evolve once it reaces Level 22.
Does natural selection deal with only plants?
No, all life evolves. Bacteria evolve, viruses evolve, protists evolve, plants evolve, fungi evolve and animals evolve. Evolution is driven by Natural Selection. So, no. The evolution of all life on Earth is driven by Natural Selection: all bacteria, plants, animals, mammals, fish, insects, biochemical pathways, behaviours et cetera evolve by Natural Selection.
When did life begin to appear on earth?
Plants have been around on the Earth since the Cambrian part of the Palenzonic Era.
Does earth shape life or life shapes earth?
Life has shaped Earth through processes such as photosynthesis, which has transformed the atmosphere, while also influencing the climate and geography of the planet. At the same time, Earth's physical and chemical environment has provided the conditions necessary for life to evolve and thrive. Both life and Earth have had an interdependent relationship, each influencing the other in various ways.
What level does ratta evolve?
Rattata will begin to evolve once it reaches Level 20.
When does infernape evolve into shiny infernape?
If your Infernape is not shiny to begin with, it will not evolve into a shiny Pokemon.
