3. What is the primordial soup theory?

Ans. The primordial soup theory proposes that life originated from a mixture of simple organic compounds in the Earth's early oceans. It suggests that chemical reactions, such as lightning or volcanic activity, caused these organic molecules to combine and form more complex molecules, eventually leading to the emergence of life.

4. What is the panspermia theory?

Ans. The panspermia theory suggests that life on Earth may have originated from microorganisms or organic molecules that were carried to our planet from space. These could have arrived through comets, meteorites, or interstellar dust, providing the necessary building blocks for life.
