Previous evidence for the world's oldest life on land came from 2.7—2.9billion years old deposits found in South Africa.

  1. Dome-shaped stromatolites, averaging three feet high and four feet wide, populate the shallow shore of an ancient sea 3 billion years ago. The Moon looms near the horizon, much closer to the Earth than it is now and therefore appearing considerably larger, but otherwise looking much like the moon we know today. 3 billion years ago the first macro evidence of life on Earth may have appeared in.
  2. Earth coalesced a little more than 4.5 billion years ago from bits of cosmic debris. Liquid oceans existed on the planet almost from the beginning, although in all likelihood they were repeatedly vaporized by the massive meteorites that regularly clobbered the planet during its first 700 million years of existence

At about 4.4 billion years, the young Earth had a mass similar to the mass it has today. The continents probably began forming about 4.2 billion years ago as the Earth continued to cool. The cooling also resulted in the release of gases from the lithosphere, much of which formed the Earth's early atmosphere. Most of the Earth's early atmosphere. The early Earth's atmosphere had a very low concentration of oxygen compared to today. 2.4 billion years ago, the oxygen concentration in the atmosphere was less than one part per billion and the iron concentration in the ocean was much higher than today How Do We Know the Earth Is 4.6 Billion Years Old?

Earth Cooling and Primitive Life (4.0 - 2.5 billion years ago ) The collision of the moon into Earth significantly impacted climate, oceans and life on Earth. Because the moon's orbit drags Earth, it slowed Earth's rotation significantly from 6 hour days to 24 hours. By having the moon in orbit, it also stabilized the Earth from wobbling 2.3 billion years ago. Earth freezes over in what may have been the first snowball Earth, though there is as yet no fossil evidence of what it looks like. 630 million years ago In our illustrations, Earth's axis is drawn as a straight red line. Giant Impact Hypothesis. The impact around 4.5 billion years ago is described in the Giant Impact Hypothesis, which is the current prevailing theory on how the Moon was formed and how Earth got its tilt. Ever since this impact, Earth has been orbiting the Sun at a slant

Asteroids and Comets: Information and Facts | National

Earth and the other planets in the solar system formed about 4.6 billion years ago. The early Earth was frequently hit with asteroids and comets. There were also frequent volcanic eruptions. Both were sources of water and gases for the atmosphere; The early Earth had no ozone layer, no free oxygen, and was very hot It's incredible to see how Earth has changed over time, particularly during the breakup of supercontinent Pangea around 175 million years ago. While Webster points out that the locations on the open source project are approximate, it's addictive to flip through the different time periods and see how the planet evolved The oldest of these have ages between 4.4 and 4.5 billion years. There are also martian rocks samples exist in the form of meteorites that fell to Earth long ago. Some of these samples have been dated to 4.5 billion years old, supporting other calculations of the date of early planetary formation
