Theories of origin of life

Answer 1

No one else has been able to propose any widely accepted theory. Darwin's theory of evolution concerns the origin of SPECIES once life already came into existence. It does not incorporate the concept of abiogenesis (life from non life) yet.

For the origin of life there is the RNA world hypothesis. Panspermia is a competing theory proposed by a couple of astronomers, but it has not gained much traction among biologists OR even astrobiologists. Some folks have proposed various crystals or clays served as a scaffolding upon which organic macromolecules self assembled. The whole question (like so many others in science) remains a big mystery.

Many religions believe in some sort of divine creation, or intelligent design as a theory of origin of life.

Answer 2

The two most widely-known are the tradition of Creation, and the theory of Evolution. According toEvolution, life developed by random processes, especially mutations.

The narrative of Divine Creation, which is contained in Genesis ch.1 and 2, states that God created the universe. This teaches us that God exists, that our lives and the world are not random, and that the created things may be assumed to contain vast wisdom in their beautiful and purposeful design. (In recent decades, this wisdom has indeed been partially revealed, through increasingly powerful microscopes.)Evolution through random mutations, on the other hand, may be understood as implying that life is an accident, that perceived beauty and wisdom are ultimately purposeless, and that our instinctive yearning for the Eternal is just an electrical impulse in our brain.
