Why would they?
The only reason’s that “aliens” would come to this planet would be to exterminate us, and take the planet for themselves, or to simply take its resources or, manage us, much like we manage the deer population. They might very well find sport in hunting us; and they might have a taste for human flesh.
Then of course we have the ET or Alf varieties, who just want to make friends and possibly eat our cats.
As a race of people, we are a violent race. While some countries are “more mature” than others, there are elements or factions in this world who are malevolent in nature, and in fact still “live by the sword!”
There are other factions that enslave us with their corrupt, power hungry, narcissistic, maniacal, psychotic view of life, bent on gaining even more power or money, damn the cost! I would ask them, how much money is enough? Writing laws by the thousands, in order to enrich their lives by taking from the peasants. No race or group is sacrosanct, they just manipulate us into believing that we are.
There is a list on the internet of the wealthiest men. Bloomberg is worth Billions; is it any wonder that he now acts like a god; telling you what you can eat or drink or smoke. Take your billions and go retire somewhere, buy an island and don’t take any guns or soft drinks.
There are factions on this earth who have been at war with one another most probably since they were in caves; learning to master fire. There is in fact nothing that we have to offer a space traveler other than entertainment, much like the Romans throwing Christians to the Lions for being unpatriotic and not worshiping their gods Jupiter, Mars, Juno and Vesta. Then they might want to do like the writers of Star Trek suggest in one episode, (original version), pitting one human against another in some sort of competitive sport where they fight to the death, with the aliens betting on which one would be victorious. Whatever a quatloo is worth in our money, maybe we should print some, just in case. Actually thinking about it that was kind of a theme, I still remember the Gorn, do you?
My personal feelings are that if we were visited by a friendly race, we would be chastised for how noisy we were as a planet, and warned not to bring our war mongering ways outside of our planet. I would in fact welcome such a visit as then, just maybe the super powers and the war mongering idiots of this world would see that there are bigger things out there other than themselves and their petty bickering. Personally, I think they are all so wrapped up in their own agendas, that they truly can’t see the forest for the trees!
They all in fact need a “time out!”
Technology has truly outpaced our humanity. We have “scientist” sending signals into space, looking for a response as well as SETI, much like the Short Wave Listeners of years ago, just listening to see what they hear.
We have more and better ways to kill one another. We have created WMD’s that will kill off the inhabitants, while leaving the infrastructure in tact. We have such a low value for human life that we call it a women’s choice vs. what it truly is “murder,” and then we make it a political lever or football in order to paint one side in a negative light. We kill innocent people, in order to make a point of how “bad ass we are” and than threaten that you had better capitulate to our god, or more will die.
As far as a race coming here to take our resources, I have serious doubts that we would be worth the trouble. There are far too many worlds out there that most likely have no life at all or possibly simple microbial life, at the beginning of its evolutionary cycle. One has to wonder if Aliens did visit us, would they consider us at the beginning of our evolutionary cycle.
Carl Sagan was a man that I admired, and while I loved his shows, his brilliant forward thinking mind, I can not help but wonder if sending a map, to where we are; out into interstellar space was a good idea. Hopefully by the time it is discovered, we will have evolved as well. If when found and we are visited what will they find? A functioning world with intelligent beings, or a world wrapped in nuclear winter?
Any alien passing by, on their way to who knows where, most certainly would listen to our broadcast, and if they could make sense out of them they would know that they would most likely be met with hostile threats or actions from some nation on this planet, probably multiple nations as the proliferation of nukes make there way into the hands of people who are not of sound mind and body, or have such twisted ideas of man and morality that most “normal” people, would not recognize them as sane. They may in fact pass us by because of the hostility that exists on this world deeming us simply not worth dealing with; just to get a few cats.
-Best to you and those that you care about!
