All of humanity has been at war since we set foot on this planet.
As usual, your moral outrage outstrips your information. There is no evidence that war, defined as deadly conflict between two or more organised groups for control of land, population, or wealth, existed before agriculture and pastoralism, both approximately 10,000 years old.
For all our claims of having evolved, nothing much has changed except we have become far more efficient at killing each other.
Um. . . that increased efficiency would be evidence that we have evolved. Unless you're the type of fool that believes evolution has a direction or purpose, in which case go talk to the godbotherers. I don't do fantasy.*
Well, I think, as do many others, that the time has come to actually evolve and stop this stupid waste of life and grow up.
Oh dear, you are that type of fool, aren't you?
* Well, not of the non-sexual variety, anyhow.
