Re: Folks Have I told you lately that I am an alien ?
Although reading your theory how one race's civilization depends on another's destruction (man vs squirrel) it is now still possible that aliens (intelligent ones) could come over in hopes of building colonies and in the process destroy mankind (to them it would be just like clearing a forest).
Man is one spiecies and its characteraristic can not be generalized blindly.
It would be unwise to assume that other spiecies would act in same fashion as humans do Now.
In my view, humans got corrupted as they got advanced in exploitaion of native spiecies of this planet ( through the course of thousands of years).
Now (after degradation during many thousand years )Humans believe that they are the rightful owner of this planet and can squander and cause devastation as much as they like.
If we are going to assume some traits of Aliens, we should compare it with the traits of earlier humans on earth. That would be a relatively fair comparison. They (human) were curious and respectful of other spiecies. So shall we assume about the any spiecies, visiting any planet for the first time, that they will be interested in exploration rather than devastation.
