Even though amino acids are famously referred to as “the building blocks of life” because living things (through the information contained within their DNA) transform amino acids (chemical structures) into proteins. Proteins have never been observed as being formed by any method other than DNA despite such icons of evolution as The Miller Urey Experiment.
Amino Acids are non-living double carbon molecules and can be assembled via chemical formations. There are 20 amino acids used by life, only manufactured by life, with left handed chirality .1 This may render some amino acids from naturalistic processes, not similar to anything discovered on meteors, and they do not come close to amino acids used by all living things on earth.
So called meteors carrying the amino acid chemical structures to earth as the means of seeding the earth for life is deceptive because these amino acid structures are nothing like those found in living organisms and
Regardless of the seeming strength of the conjecture, elements which compose amino acids (carbon, hydrogen, oxygen, and nitrogen are abundant on earth) and therefore generically amino acids (especially right handed) are abundant and can formed easily under laboratory conditions. As an example, amino acid supplements for humans (and animals) are manufactured in the lab similar to how pharmaceutical drugs are created. However, the amino acids used by living organisms, manufactured only within living organisms, have NEVER been found in nature, through experimentation, or on any meteor.
We have found common denominators observed in biology within all living things: All life contains DNA, all life uses the same 20 left-handed amino acids, all life is comprised of cells with highly specialized enzymes, membranes, and structures. Natural processes for amino acid formation from experiments, nature, or meteors are at best highly imaginative and at worst outright frauds.
