Quizplus · Accepted Answer

The earliest forms of life on Earth existed around 3.5 billion years ago, when there were no living organisms on the planet. Therefore, the only way for them to obtain nutrients was from the abiotic synthesis of organic molecules, such as amino acids, fatty acids, and sugars. These molecules were formed from simple inorganic compounds, such as water, methane, ammonia, and carbon dioxide, through processes like lightning, volcanic activity, and intense UV radiation. This is known as abiogenesis, and it is the most widely accepted scientific theory for the origin of life.
