How did life originate?
The major hypothesis are various versions of Abiogensis. The first self-replicating system has not been determined, but the replicating molecular systems have been established. Initially, the environment contained the precursor compounds and the amino acids are not major candiates for the origin of life and they were likely late comers. The amino acids in modern proteins are left handed and there is no reason to believe that the first life evolved proteins. Even if it did, selective assortment of left handed for structure and right handed for energy have likely occurred at some point.

What is the origin of life?
When considering how life began, there are only two options. Either life was created by an intelligent source (GOD) or it began by natural processes. The common perception presented in many textbooks and in the media is that life arose from non-life in a pool of chemicals about 3.8 billion years ago. The claim by evolutionists is that this formation of life was the result of time, chance, and natural processes. One widely used example of how life could have formed by natural processes is the Miller-Urey experiment, performed in early 1950’s. Miller’s objective was not to create life but to stimulate how life’s basic building structures (amino acids) might have formed in the early earth. In the experiment, Miller attempted to simulate the early atmosphere of earth by using certain gases, which he thought might produce organic compounds necessary for life. Since the gases he included were water, methane, ammonia, and hydrogen do not react with each other under natural conditions, he generated electrical currents to simulate some form of energy input such as lightening and was needed to drive chemical reactions. The result was production of amino acids. Many textbooks promote this experiment as the first step in explaining how life could have originated but there is more to this experiment than what is...
