Which of are proposed theories of how life came about on Earth?
Some proposed theories on the origins of life on Earth include abiogenesis (life arising from non-living matter), panspermia (life arriving on Earth from elsewhere in the universe), and the RNA world hypothesis (life starting with self-replicating RNA molecules). These theories aim to explain the transition from non-life to the first living organisms on Earth.
What came first to earth as things in the eras of the earth?
The first things to come to Earth were simple single-celled organisms around 3.8 billion years ago in the Precambrian era. These early life forms eventually evolved into more complex organisms over millions of years.
What are proposed theories of how life came about on Earth?
Some proposed theories for the origin of life on Earth include the primordial soup theory, which suggests life arose from a combination of organic molecules in Earth's early oceans, and the panspermia hypothesis, which suggests that life may have been brought to Earth from elsewhere in the universe. The RNA world hypothesis proposes that RNA molecules were the first self-replicating molecules that eventually led to the development of more complex life forms.
