　　　Introduction

　The information that gene holds is not useful if there is not a cell system. It is considered that the cell system was born at first. The chemical evolution was carried out as the result of births and disappearances of the systems. The first life was born in such a ecosystem. The beginning of life is the beginning of the ecosystem of atoms. Every creature organizes chemical reactions in a body.

　The electronic state of every atom in a body becomes the most suitable state for a situation through the interaction among the surrounding atoms. The carbon atom makes bond between various atoms, i.e. hydrogen atom and chlorine atom and metal atom. A branch in a molecule is formed by the inter-carbon bond of single or double or triple. Various atoms in carbonated water are able to make covalent bond with the carbon.

　The seawater in the early earth was carbonated. The carbonated water was changed by oxidation of iron via the eruption of volcano. The electronegativity of carbon (C) is larger than that of hydrogen (H). So, the iron atom (Fe) takes oxygen atom (O) from CO2. The free carbon atom bonds to iron atoms owing to the electronegativity. The product of iron carbide (Fe3C) reacts with water. The reaction produces organic molecules and hydrogen molecules [1]. Those molecules form a bubble in the water.

　As shown in the photograph on this introduction, bubbles are produced by mixing with iron and carbonated water. The reactions associated with oxidization of iron atom in carbonated water realized the production of bubbles. A chemical evolution was carried out as the result of ecosystem of bubble.
