A team of chemists working at the MRC Laboratory of Molecular Biology, at Cambridge in the UK believes they have solved the mystery of how it was possible for life to begin on Earth over four billion years ago. In their paper published in the journal Nature Chemistry, the team describes how they were able to map reactions that produced two and three-carbon sugars, amino acids, ribonucleotides and glycerol—the material necessary for metabolism and for creating the building blocks of proteins and ribonucleic acid molecules and also for allowing for the creation of lipids that form cell membranes.
Scientists have debated for years the various possibilities that could have led to life evolving on Earth, and the arguments have only grown more heated in recent years as many have suggested that it did not happen here it all, instead, it was brought to us from comets or some other celestial body. Most of the recent debate has found scientists in one of three chicken-or-the-egg first camps: RNA world advocates, metabolism-first supporters and those who believe that cell membranes must have developed first.

When anyone asserts their belief as fact, in the face of observable, repeatable phenomena, unfortunately, he registers as an ignorant crackpot.
when you have observed how life began on earth and repeated the process in a laboratory, be sure to let us know
otherwise, anyone that thinks they know how life began on earth is an ignorant crackpot

Who says they know? There are plausible theories, but that isn't the same as knowing.
And many fools reject the theory of evolution, despite the overwhelming evidence in its favor. These people do not care about evidence. Their ignorance is, to them, just more evidence that a magical sky daddy exists.
