When the Earth was young, approximately 4.5 billion years ago, it was a molten mass of rock and metal, characterized by extreme volcanic activity and a hostile environment. The surface was primarily covered by magma oceans, with occasional landmasses emerging as the planet cooled. The atmosphere was thick with gases like carbon dioxide, ammonia, and water vapor, with little to no oxygen, making it inhospitable for life as we know it today. As the planet continued to cool, water began to accumulate, eventually forming the early oceans.
