Scientists currently think that life got started between 3.8 and 3.5 billion years ago, probably less than a billion year after the formation of the Earth. It is certain that life existed by 2.7 billion years ago.

What is the theory in science of how life was started?

The theory of how life started is known as abiogenesis, which proposes that life emerged from non-living matter through natural processes. This theory suggests that simple organic molecules eventually formed more complex structures that evolved into the first living organisms. Scientists investigate this process through experiments and studying early Earth conditions to understand the origins of life.


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.

Why do scientists think life began in africia?

Scientists believe life may have originated in Africa because the continent has a diverse range of habitats and a long history of supporting life. Fossil evidence suggests that early human ancestors originated in Africa, leading to the idea that life itself may have emerged there as well. Additionally, Africa's unique geology and climate are believed to have provided favorable conditions for the development of early life forms.


True or false Scientists think that the first life forms on earths probably did arise from nonliving materials?

True. Scientists believe that the first life forms on Earth likely arose from nonliving materials through a process known as abiogenesis. This theory suggests that simple organic molecules gradually evolved into more complex structures that eventually led to the development of life.
