Around 3.6 billion years ago, a creature on a mysterious craft passed through the solar system was crashed into a planet called the Earth.
At that time, the creature could not survive on its own, so that it melted itself into the earth by a single cell. Consequently, the Earth began to be formed with the most suitable living things.
As a result of the evolution, it gave a rise to a photosynthetic organism, using sunlight as a direct source of energy.
Some of the oxygen produced from photosynthesis melted into the ocean and created a massive amount of iron oxide while other was released into the atmosphere, which created an ozone layer in the stratosphere of the Earth.
The early single cells recognized each other as being part of the first organism that led cell fusions and birth of eukaryotes. Then,the eukaryotes evolved into multi-cellular cells as they form colonies.
As these cells evolve individually, they transformed into the most suitable state for the Earth environments with containing the memories of the first living things each.
However, the number of population compared to the evolution states has increased so rapidly that all cells faced a critical condition.
It does not meant that these organisms have a brain which is able to think rationally although they had part of some memories from their first lives. Due to the memories, they surpassed the increase of population by blocking heat within the cells and lowering their temperatures.
The Earth was covered by these cells therefore the dropped temperature of them meant the decreased temperature of the Earth. The Earth faced the Snowball Earth status.
Then, at some point, the cells exploded the inner heat in an instant, which caused the Cambrian Explosion*.
*The Cambrian Explosion: A geologic event approximately 542 million years ago in the Cambrian period when the animal species appeared in the fossil record.

This story ends about thousands of year later when the first craft which the first creature came on board can be recreated by human beings after repeated the evolutions of them.
The first creature utilized ‘the species specificity’ on the planet, as a ‘life support system’, when it could not live on its own.
The saints and great philosophers, leaders, inventors, scientists, and so on existed in the human history had some of the original genes of the first living things.
Human existence, and the history of the civilizations are nothing but the process of the first creature to escape this planet and go back to its homeland.
