Home to millions of species of life, Earth is currently the only known heavenly body with life. The planet formed 4.54 million years ago and life appeared about a billion years later. Over the years, the planets biosphere began to change,creating life forms as well as the ozone layer.
Our planet's scientist have been able to discover parts of our planet's past. 4.5672 ± 0.0006 billion years ago, what we believe as the earliest solar system fragments. 4.54 billion years after their formation,(with a small uncertainy of 1%)a disklike cluster of dust called a Solar Nebula was left over after the Sun's assumed formation, which created the other planets. This "construction project" wasn't completed until about 10-20 million years later.
Formation of life
The earliest found organisms were almost useless in the study of Human Evolution, as they appeared rather featureless and boring since their fossils looked like small rods. Luckily, another scientific find was confirmed as about 3,000 year old fossilized bacteria. Other fossils dated to about 3,500 years old(with some geomatrical evidence of them being around 3,800 years old).However, some scientist disagree about this evidence having a biogical formation.
