The problem is the humans who are in control of this planet are obsessed with weapons and war.Interesting thought,but if you believe them to be beyond us spiritually and mentally. Maybe they just never made weapons as powerful as the ones humans have. This would give reason to believe aliens might fear man. People assume just because they have sophisticated spacecraft,that they have more advanced weapons. When weapons may not even be a real area of study for them. Just look at earth for example,not every group of people spend energy on weapon advancement,biological warfare and nuclear arms. But if you believe in different species. Youd kindve have to assume there is a species of them that wants the smoke,and eats,sleeps,shyts weapons.
Why are they so obsessed with weaponry and control? Is it only to subjugate other humans, or is there another reason?
