Earth's story begins in space. Its quiet and multiple "planets" are just large collections of rock and dust. The small planet Earth was just a tiny rock mass compared to most things around it.
After many years, one day the Earth crashed into another planet. After the crash the Earth's overall size became much larger while the gravity from the new planet was used to form the moon around our Earth. This allowed the Earth to grow by collecting rock and dust while orbiting.
The Precambrian Era is the longest known and recorded era in Earth's history making up 87% of earths life so far and is also the start of a long line of chain reactions leading up to the making of the beautiful complex planet we call home. during the Precambrian era the earth went through many changes, the Earth was once just a large ball of fire and was uninhabitable by anything. This large ball of fire was the start of the Earths life and was an important part in the development of the earth as we know it. Overtime this large ball of fire was cooled down as asteroids fell from space carrying tiny amounts of water and over many years the water accumulated and began to cool the earth into a large rock and water mass. More time passed and the Earths oceans began to form as the molten rock close to the earths core sent large volcanoes to protrude from the oceans.
The Earth also froze completely over and went through multiple changes but not just on the surface but also in the atmosphere and in the water and on land. The earth complexity is unmatched by any known planet as the earth has somehow gone through many changes and eras and species that make the earths history. Throughout the Precambrian Era the Earth went through multiple asteroid and meteor showers to shape it into the planet it is today but with so much time spent in this era it is no surprise. When earth was finally habitable we saw the first form of life begin to surface as asteroids crashed into the oceans giving life the chance to start as simple single cell organisms and will eventually grow into greater beings .
The Paleozoic Era lasted until about 245 million years ago. In this specific time of the Earth's life, other life began to change. Deep in the oceans of earth life began to diversify and change so that there multiple different species of animals each with different qualities that made them distinguishable from each other. Soon the oceans were filled with vertebrates and invertebrates. animals with spines and animals without.

The Paleozoic Era also had animals diversify as amphibians and arthropods. Soon the Earth had many creatures and species in its oceans and seemed unstoppable. Sadly, almost no creature was safe as within a few years of the Earth new lively oceans development there was the largest mass extinction in any recorded fossil records. In a blink of an eye, 90% of earths marine life went extinct leaving almost nothing left alive until the next era.
