Today, we've realised that the very first life on Earth was indeed originated from abiotic surroundings. In fact, organic molecules have been successfully generated from abiotic elements by scientists To understand how this creation of life from abiotic material occured, we have to consider a critical idea. Life originated from its abiotic surroundings. Thus, it is important for us to learn about the physical and chemical environments of the primitive Earth. The atmosphere of primitive Earth consisted of reactive, naturally availabe, molecules: Nitrogen (N2), water (H2O), methane (CH4), and ammonia (NH3), etc. These molecules what was ne
