I am well aware of the human concept of there being a struggle between forces of dark and light over the control of the Earth.
It is the same in character within humanity, within religion and bled over to our subjects of alien life.
I am also well aware that this concept only survives in the mind of humanity.
None of any of all the known races in all the known Universes share the same concept we have of struggles between forces of dark and forces of light.
All the races visiting Earth are friendly to humanity.
Some races who used to visit were not of the same exact intention, but none were here for the purpose of abusing humans.
Some just needed things that were free for the taking.
That is no longer so due to the organization of our visiting races.
