Born again humans

Adam and Eve are innocent space settlers unwillingly caught up in the middle of the first confirmed alien encounter.
The ensuing three-sided game between indecipherable aliens, over-zealous robots and an estranged humanity turns out to be the early stage of a diplomatic war.
As things go from seriously wrong to considerably worse, clueless heroes and vain villains arise from all sides in a multifaceted struggle of anticipation and deception, but where miscalculation takes the lead.
In the hands of such people, displaying a sub-optimal understanding of death and a total disrespect for life, the survival of the human civilisation ranges indeed from the utterly uncertain to the plain gloomy. Such a situation would be labelled as a paradigm shift by the scientists, whereas the religiously-inclined would certainly behold it in awe as the long-awaited apocalypse.
