What time period was the earth created in?
About 4.5 billion years ago.
It all started with a cloud of cold disturbed dust particles from a nearby supernova, which started to collapse under gravity forming a solar nebula, a huge spinning disk. As it spun, the disk separated into rings. The center of the disk became the Sun, and the particles in the outer rings turned into large fiery balls of gas and molten-liquid that cooled and condensed to take on solid form. About 4.5 billion years ago, they began to turn into the planets that we know today.
Initially, Earth’s surface was continuously bombarded by meteorites as well volcanic action. Condensing water vapor, probably from ice delivered by comets, accumulated in the atmosphere and cooled the molten exterior of the planet to form a solid crust and produced the oceans. It was also during this period that the Earth’s satellite, Moon, was formed, after a body the size of Mars struck the early Earth. About 3.8 billion years ago, Earth cooled significantly and life forms began to evolve.
