In order to make proteins, a cell uses ribosomes, which itself is a structure made out of proteins. The first ribosome couldn't have been created with the help of ribosomes though, as the ribosomes weren't there yet! So where did the first proteins came from? Before the advent of ribosomes, which, when they arrived on the scene (in some primitive form), subsequently could be used to make increasingly complex proteins.
In prokaryotes, ribosomes are roughly 40 percent protein and 60 percent rRNA. In eukaryotes, ribosomes are about half protein and half rRNA. Ribosomes are usually made up of three or four rRNA molecules and anywhere from about 40 to 80 different ribosomal proteins.
Amino acids were abundantly present though before ribosomes came into existence. Most of them were left-handed as is life itself (look at the Softenon babies). You can compare this with the matter-antimatter problem in physics (which is not really a problem in my theory, but I won't bother you with that sh*t). A scenario to achieve is easy to come up with.
While competing-self-replicating molecules were present too, they could make good use of them. A rudimentary ribosome emerged (with earlier formed proteins, by accidentally combined amino acids so these proteins came first, actually).
Behold the creation of life! Once started life exploded, leading to us (some say that there is some kind of hyper evolution going on: the rise of the robots with no ticker, no tears, no feelings but a high calculating power).
Is my reasoning reasonable?
