It seems like we are always at war with each other on earth because we all believe in different ways of living our lives and have issues with others over being wronged in the past – some of these ideas clash badly and even want to destroy certain belief types.

You just have to wonder if Aliens went through the same problems and what they may have done to over come these problems.

Maybe they could help us solve our differences and unite us, or maybe their beliefs could be problematic for us and destroy our way of life.

ISIS is an extremist religion that is weaponised to attack our way of life and doesn't seem to want to work things out – if ideas like theirs become the majority belief structure then advanced progress becomes much harder to achieve

If you look at what's happening in US univerties you can see another belief structure trying to take hold right now – It shows how fragile our way of life really is

Maybe Aliens saw the flaws in language/different ideas and decided to do away with it and adopt a better way of communicating/overall idea of what they were aiming to achieve as a species, or maybe they just evolved something that hasn't been imagined yet

(Maybe this isn't the sort of thing what you want posted here)
