I agree and would add that-
There must be other intelligences in the countless number of planets in the universe.
Perhaps some of them have technology and have evolved beyond the fighting stage into working together for the betterment of everyone.
The reason that it is within the realm of possibility, is because the Earth is only about 4 billion years old and we have a form of intelligence, yet the universe is something like 14 billion years old, therefore, there would be lots of time for such intelligence to develop on other planets in other galaxies.
