To kick off this piece, I am going to work on the assumption that Aliens are real ad that they live on far away planets, and have been for some time. A jump without any solid evidence, I know...but humour me.
What I would like to look at, is how we perceive any type of alien contact, when and if it ever occurs.
Humans are a pretty arrogant species and we do like to think that our little ball of compact dust hold a significant place in the universe. Perhaps as we, the travelers are so important.
There have been and probably will be, lots more accounts of aliens landing o abducting us humans, giving us special messages about saving the planet. I for one cannot see why any race of aliens would travel (however they travel across millions of miles) to warn us about saving ourselves, unless they really are higher beings and universal do gooders.
Then there is the theory that they are out to destroy us and take over our planet as it requires our vital resources. We have established that there are dozens of earth like planets littering the galaxy around us. Most may have no life on at all. And these are the ones we know of. There are probably thousands more. Why would our aliens not simply milk the planets with no life and no prospect of resistance?
Further, if there was an alien race that had found a way to travel through space and time, surely they would have invaded by now, before humans 1) Destroy their target further 2) The earth's population grows 3) We develop more effective weapons....to name three points that would make it more difficult for them, if they waited, I am sure there are more as well.
If they are anything like humans, we are mere experiments to them. When we find a new species, we learn all we can about it. We would assume a more advanced alien race would do the same when coming across us. (as we would do if we ever found life on another planet, moon or other body)
We are not vital to the survival of the galaxy and nor is the planet we call home. Sadly, we are not even a spec in the universe and if we vanished, the universe will carry on, not fold in on itself.
To me this is the reality of any alien visitors....it is not to destroy us, colonize earth or really try all they can to save us....we are amusement...a species to learn about..and maybe from. That's all....
