At its beginning, Earth was unrecognizable from its modern form. At first, it was extremely hot, to the point that the planet likely consisted almost entirely of molten magma. Over the course of a few hundred million years, the planet began to cool and oceans of liquid water formed.07-Jul-2021
Steps in the accretion process:
3.7 billion years The earliest life forms we know of were microscopic organisms (microbes) that left signals of their presence in rocks about 3.7 billion years old.
Over time, the bombarding slowed down and Earth began to look less like a fireball and more like a planet. Early volcanoes put out gases that helped create the atmosphere. Some of the rocks that hit Earth came from far away, beyond Jupiter and Saturn, and had ice in them.
When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle, and a solid crust.
From space, Earth looks like a blue marble with white swirls. Some parts are brown, yellow, green and white. The blue part is water. … The northernmost point on Earth is the North Pole.
In July 2018, scientists reported that the earliest life on land may have been bacteria 3.22 billion years ago.
Homo sapiens, the first modern humans, evolved from their early hominid predecessors between 200,000 and 300,000 years ago. They developed a capacity for language about 50,000 years ago. The first modern humans began moving outside of Africa starting about 70,000-100,000 years ago.
Many religious persons, including many scientists, hold that God created the universe and the various processes driving physical and biological evolution and that these processes then resulted in the creation of galaxies, our solar system, and life on Earth.
