Presumably 4.6 billion years ago, the Earth formed under extreme heat and pressure making the atmosphere extremely hot. During this time, known as the Hadean period, our young planet was being constantly bombarded by asteroids, comets, and meteors, which contributed to the immense heat in the atmosphere. Millions of years later, the planet was pulled into the orbit of the Sun due to its gravitational pull and started to cool down. As the Earth cooled down, its atmosphere began to take place, making life suitable for existence. Large bodies of water began to surface and covered the Earth after the first Ice Age. The first ever sign of life on Earth appeared in these large bodies of water. Eventually after millions of years, the first species came out of the waters and started to surface to continents of the world. The continents during that time were all conjoined together as a supercontinent, known as Pangaea. As another million years went on, the continents split apart forming what it looks like currently on a world
