The history of Aiers concerns the development of the planet Aiers from its formation to the present day. Nearly all branches of natural science have contributed to the understanding of the main events of Aiers's past. The age of Aiers is approximately one-third of the age of the universe.
However, for long a problem for the planetary history was that in five occasions there happened great geological changes, unexplained by natural causes: -between the 300.000 to the 220.000 b.a.H, Around the 23.500 b.a.H, the 50 to the 100 a.a.H and finally 2675-2700 a.a.H-. This for long puzzled the scientists.
Another puzzle for them, aside of the sudden geological changes that re-shapped the surface of Aiers, were the biological changes that happened, as life in Aiers only began around the 260.000 a.a.H, with the apparition of the aierian peoples only at the 200.000 a.a.H: this caused great problems for modern science, as it didn't gave enough time for the species living in aiers enough time to evolve.
Aiers suddenly developed an atmosphere around 300.000 years before the Apparition of Humanity, without natural causes explained.
The first life forms appeared between 260.000 years ago. Photosynthetic life appeared in an impossible short time of 220.000 years ago, which wouldn't have provided enough time to enrich the atmosphere with oxygen, as only 10.000 years later would arise complex multicellular life. Then during the next 10.000 years Aierian life experienced a rapid -unnatural- diversification of life, appearing -without any previous evolution in Aiers- the Aierian peoples at the 200.000 a.a.H in Zarhuy.
Aside of the five geological cataclysms of Aiers, Geological change has been constantly occurring on Aiers since the time of its formation and biological change since the first appearance of life. Species continuously evolve, taking on new forms, splitting into daughter species, or going extinct in response to an ever-changing planet. The natural process of plate tectonics has been changed by the Cataclysms, who stole their protagonic role in the shaping of Aiers's oceans and continents, as well as the life they harbor.
