Considering that 2 and a half galaxy wide species went extinct ( ancient humanity, forerunners with ancient human war 1/2 aprox, forerunners flood war). 20 billion human deaths during covenant genocide, about same number on covenant side (grunts and jackals are easy target, ship combat gave alot of losses from covenant side even tho they almost always won). Plus the deaths of nature, conflicts inside species. The estimated amount of death of humans of all time is 110 bill deaths [url=http://wiki.answers.com/Q/How_many_people_have_died_since_beginning_the_of_time]source[/url] [quote]Starting from 55,000 B.C.,when modern -blam!- sapiens appeared,taking into account that all population data is a rough estimate and assuming a constant growth rate up to modern times it has been estimated that 106 billion people have died since the dawn of the human race.[/quote]. Thats only our humanity, not considering covenant, ancient humanity, forerunners and the precursors. Ofcourse this is nothing compared to Yuuzhan Vong who alone, killed 365 trillion in starwars (this is crazy) but im just interested. Sorry, please ignore the "a" in the title.
