Best Answer


The primitive atmosphere contained gases like CO2, C0, N, H2, etc. Water vapour and metallic carbides reacted to form the first organic compound, methane (CH4). It is suggested that simple one celled organisms somewhat similar to today’s cyanobacteria (blue green algae) were present on earth about 3500 million years ago. With the addition of oxygen into the atmosphere, methane 'and ammonia began to disappear as they got oxidised forming CO2 and N2 respectively. The reaction of oxidaton of CH4 is

Hence, these interacted later to form an array of simple organic substances which played a major role in the chemical evolution of life
