Aliens, Integration, Peace

Humanity alone in the Universe? no evidence for none, but that's obvious that Humanity is complex and we each are very different, the origin can be multiple, also from outside the planet and also from the planet, mixed, multiple species. The highest integration level must be Peace, other ways couldn't exist. Can be also Species which Human perceptions don't perceive The knowledge of Humanity may have the borders, that we don't understand and percept that may be forms of Life even on Stars. Totally an other kind of Species. If Peace wouldnt be the highest level for Integration the Universe wouldnt exist
