>We don't know who invented slavery and we'll never know but when European explorers arrived they did not introduce the concept.

Wrong; the System of Racism as it is known today is entirely an invention of White European Countries. Prior to their institutionalizing of Racism on pseudo-scientific lines it was merely simple enslavement of the loser by the victor on a case-by-case basis. Also not all Countries/Kingdoms engaged in this. It is only with the expansion by Europeans that the idea of "Races" some of which were considered inferior by birth/definition because of skin color(black/brown/yellow/red), facial features(Caucasian/Negroid/Mongoloid), lack of understanding of native cultures(civilized/uncivilized), etc. became Systematized/Institutionalized and given legitimacy using what we know today as pseudo-science.

> Nor did they introduce war, superstition, poverty, starvation or inequality.

But they increased it exponentially, devastating entire countries/civilizations/cultural groups/social groups/etc. Much of the mess in the World today particularly in Africa, Middle East and South Asia has its genesis in their colonial past.
