The Big Bang Theory is the most accepted theory regarding the origin of the planet earth and the existence of different life forms on it.

No scientist has yet been able to create a living cell from organic molecules. The conundrum is that on Earth today all life comes from pre-existing life. He suggested that phosphoric salts and ammonia in the pre-biotic pond somehow had been changed chemically by heat light and electricity leading to the synthesis of the.
