2) create and use high tech
3) philosophize about our own thinking
4) have sex purely for pleasure
5) create artificial representatives of our own selves through robotics
6) manipulate the gene structures of other species
7) create and use clothing.
8) capture and tame the most dangerous species for fun, profit, food, and entertainment.
And the list of stuff differentiating us from animals goes on and on.
Exactly how do you think that we are notan alien species?
So the development of our intellect by always figuring out how to harness and use the things around us and make things easier for us to do means we
are alien? So expanding on your theory, when other aliens finally were able to get off of their planet and go forth into the cosmos, it was only due
to a different alien species that colonized that planet? And so on and so on? So where does it begin? Was there originally a "God" alien that
started the whole thing?
And with the same type of "evidence" that "proves" we are aliens or that aliens are on this planet, we can question your points:
1) Maybe animals have figured out how to go into space - after all, absence of evidence does not prove they have not gone to space.
2) Maybe animals have created and are using high tech. They are just keeping it hidden so we don't know about it. Probably hidden in the same place
as the crashed saucers.
3) Just because we can't speak animal languages doesn't mean they aren't philosophizing. We just are too dumb to understand.
4) Actually, we can't state whether animals have sex for pleasure or not. Several species appear to have sex purely for pleasure. The Bonobos, for
example, even use sex for greetings and conflict resolution.
5) Just because we haven't discovered robotics made by animals doesn't mean that they don't exist.
6) No proof of this. We just haven't discovered the true capability of animals. They hide it from us.
7) Maybe they are so advanced that they don't feel the need to cover up their "bits".
8) Again, they may be so advanced that they see this as uncivilized.
So, your list of "differences" is merely a list of things that the animals haven't "disclosed" to us. Maybe it's the animals who are the aliens
and are pretending to be inferior.
but they are fairly harmless,(just be careful when saying goodbye)
