Human-Isu War
the first war was a fictional war between early Humans and those who came before. much is unknown about the war but it led to the first civilisation not seeing the signs of a pending appocolypse which led to the destruction of almost all of both races and much of the eart
Causes
seen in the truth video, Humans are being used as a work force (slaves) by the first civilisation. they use the pices of eden bend the will of man to make them work but the Half breed Humans seem to have developed an immunity towards the piece's of edens effects allowing two early Humans called "Adam and Eve" to escape the factory (more commonly known as the garden of eden) and bring with them a captured piece of eden.
this most likely caused the war and also inspired the story of the garden of eden, with the first civilsation being the creator or "god" who threw them out. Templars use the other story as a cover up to control all of humanity.
the war
it seems that those who came before had better technology but the humans were many and built to survive in any conditions. this survival instinct may have been later known as evolution.
the war was cut short as the massive solar flare burnt the earth
aftermath
since the first civilisation, the only people who could save the earth, did not see the signs of the pending apocolypse, the earth and most of its inhabitants were burnt. the first civilisation lost most of them which resulted in the humans winning.
the blast could have caused the last great ice age which triggered mans fast evolution.
