Quick answer while there are many theories as to how life began on earth, no theory has been accepted as truth, according to nbc news biologist diana northup from the university of new mexico says this is because it's hard to prove or disprove many of these theories.
The theory was appealing, and solved many of the basic problems with existing ideas that life may have been carried to earth on a comet or asteroid or that genetic material emerged first - the rna world hypothesis.

According to this theory, life began in a pool of water, called 'soup' because it was rich with the kinds of chemicals needed to make life suddenly something happened - perhaps a bolt of lightning hit one of the pools - and the chemicals reacted and formed more complicated chemicals.
A totally new and highly controversial theory on the origin of life on earth, is set to cause a storm in the science world and has implications for the existence of life on other planets. According to some versions of the theory of panspermia, meteorites are responsible for bringing the first primordial life to earth the theory holds that either very simple forms of life or the materials necessary for it to form are carried to earth on comets or fragments of asteroids. According this theory, the origin of life on earth is the result of a slow and gradual process of chemical evolution that probably occurred about 38 billion years ago chemical evolution refers to molecular evolution is the process of evolution at the scale of dna, rna, and proteins. A theory that speaks to the origin of life on earth and other rocky planets posits life as an information system in which information content grows because of selection life must start with minimum possible information, or minimum possible departure from thermodynamic equilibrium, and it requires thermodynamically free energy accessible by means of its information content. The earth is about 4,500 million years old there is evidence that living things existed on earth at least 3,500 million years ago no one was there to record how life began.
Life began in the ocean the big bang theory is currently the most prevailing theory that explains the formation of earth roughly 13 billion years ago substantial scientific research and theories are in agreement that when earth was born, conditions on earth was harsh. More than 36 billion years ago, a major transition was made on earth whereby a dilute, swirling cauldron of simple chemical soup made a critical step towards creating the building blocks of life. Some question whether life began on earth at all, asserting instead that it came from a distant world or the heart of a fallen comet or asteroid some even say life might have arisen here more. The theories i have heard about how life on earth began are interesting but the one that makes the most sense to me is creationism there are numerous theories that mankind has come to believe how life began on earth.
Actually, the theory of evolution is false life didn't come about by chance, rather, there's a living god (who's name is jehovah) that designed and created everything we know today even scientists don't have enough evidence to prove the theory of evolution. Contracting earth theory, or geophysical global cooling if you want to get all science-y about it, was a theory before the idea of plate tectonics ever came about that said the earth is actually getting smaller over time, and the shrinking earth is what causes natural disasters as well as the natural wonders of nature, such as mountain ranges. Scientists do not know how life began on earth they do know that the early earth's atmosphere was very different from the atmosphere now in 1952, stanley miller was working with harold c urey designed an experiment to see how complex organic molecules might have formed under the conditions of early earth. 7 crazy theories about life, the universe & everything article by sa rogers , filed under conceptual & futuristic in the technology category our universe is located inside the black hole of another universe - or it's just a holographic projection - or it's all one big computer game being played by bored super-intelligent aliens.
Life on earth began more than 3 billion years ago, evolving from the most basic of microbes into a dazzling array of complexity over time but how did the first organisms on the only known home to life in the universe develop from the primordial soup one theory involved a shocking start another idea is utterly chilling. Primitive earth the origin of life on earth is a highly curious thing in fact, many scientists have dedicated their entire lives to finding out how life came to be on earth. The idea that life began as clay crystals is 50 years old in 1966, a young chemist suggested a radical new theory for how life might have begun on earth fifty years on, we ask if there was any. If we accept the warm little pond theory or other theories that life began on earth, then life on earth does not begin in just one point in time but in various different time when such conditions for life evolution are present.
