• Abiogenesis or biopoiesis is the natural process by which life arises from non-living matter such as simple organic compounds. The earliest life on Earth existed at least 3.5 billion years ago.

• Fossilized cyanobacteria were found in 3.5 billi/on years old geological structures called Precambrian Stromatolites.

• These are supposedly the first living organisms to be discovered.

• Earlier the Earth was a huge revolving flaming ball filled up with volcanoes and lava at every stop.

DARWINISM• The meaning of "Darwinism" has changed

over time. The term "Darwinism" is often used by creationists as a criticising term in reference to beliefs such as atheistic naturalism, the term has no negative connotations, being freely used as a shorthand for the body of theory dealing with evolution, and in particular, evolution by natural selection.

Theory Of EvolutionDarwin's Theory of Evolution :-Darwin's Theory of Evolution is the widely held notion that all life is related and has descended from a common ancestor: the birds and the bananas, the fishes and the flowers -- all related. Darwin's general theory presumes the development of life from non-life and stresses a purely naturalistic "descent with modification". That is, complex creatures evolve from more simplistic ancestors naturally over time. In a nutshell, as random genetic mutations occur within an organism's genetic code, the beneficial mutations are preserved because they aid survival -- a process known as "natural selection." These beneficial mutations are passed on to the next generation. Over time, beneficial mutations accumulate and the result is an entirely different organism (not just a variation of the original, but an entirely different creature).
