"It's incredible to see people say all ET life in the universe is evil, especially if they believe in a loving God.
Try looking in the mirror. How could anyone think Earth is morally superior?
Dark forces influenced Earth, but humans have always had free will to choose morality."

It's because humans have been conditioned to believe anything which they don't understand must be evil.
Then evil withholds the information which would lead to anyone learning truths they want to remain hidden.
Once you're on the awakened path you quickly learn that black cannot exist without white and dark without light and good without evil therefor if there are evil aliens then in probability there should be benevolents.
Which there are!
They hide the truth about all aliens because it leads back to humans being the aliens!
