How did life begin on the planet? by Rubaku chan https://padlet.com/pgissel6/o5nzncctrcmm2owd Stefany Peña en-us 2021-11-13 03:35:33 UTC 2026-03-15 22:24:39 UTC hello@padlet.com https://padlet.net/icons/png/1f30e.png pgissel6 https://padlet.com/pgissel6/o5nzncctrcmm2owd/wish/1888418567 While there are many theories about what happened on our planet that led to the development of life. Earth has been bombarded by countless meteors, asteroids and comets throughout its more than 3 billion-year history, and some theorists believe that life arose as a result of a cosmic collision. When one of these massive comets entered Earth's atmosphere, it could have contributed trillions of pounds of organic matter, possibly far more than existed on the planet prior to these icy bombardments. The energy from the impact, combined with these basic organic molecules, could have contributed to the emergence of life.

  • No one knows how life began on our planet. Experiments show that the chemical elements of life can form in space or on Earth. What we do know is that, when it forms, life is incredibly resilient. Living bacteria have been found in frozen Antarctica, in boiling water, and in rocks up to 5 kilometers underground. Earth has become the only world in our Solar System with an atmosphere rich in this factor.
