The simple organic compounds that may have first evolved in the direction of origin of life on the Earth must have been:

Different chemical molecules in the environment react with one another, absorb energy, and produce amino acids, which are the building blocks of proteins. Permutation and combining of molecules results in nucleic acids, which transfer information from generation to generation.
Proteins and nucleic acids are two fundamental cell components that aid in the origin and survival of life on Earth. Proteins define a cell's boundary by building a selectively permeable limiting barrier, while nucleic acid, which is a self-replicating entity, is the bearer of information from one generation to the next.
