Billy: I mean if they're so smart, why don't they just reveal themselves to us and get it over with?"
George: Why don't they reveal themselves to us is because if they did it would cause a general panic. Now, I mean, we still have leaders upon whom we rely for the release of this information. These leaders have decided to repress this information because of the tremendous shock that it would cause to our antiquated systems. Now, the result of this has been that the Venutians have contacted people in all walks of life - all walks of life. [laughs] Yes. It-it-it would be a devastatin' blow to our antiquated systems - so now the Venutians are meeting with people in all walks of life - in an advisory capacity. For once man will have a god-like control over his own destiny. He will have a chance to transcend and to evolve with some equality for all.
--Easy Rider, the movie
If there are aliens, and they are advanced enough to get here, they are advanced enough to get here undetected. They are advanced enough to study us and know all about us. They are advanced enough to know that a gigantic swirly light show in the sky would be the wrong approach. I mean: Why do that?
If they were going to come here, it seems that their motivation for doing so would be one of the following: 1) Malicious - they wanted to eat us or steal our resources, 2) Friendly - they are so advanced, and they want to share their technology and wisdom with us on a good will mission. Period. Am I right? So in either of these cases, I can't see why they would do the big swirly thing, you know? If they were coming for malicious reasons, their robot tractor/tank/harvester things would land here and just start shredding us. If they're advanced enough to get here, they're advanced enough to have killer shredder robot tractor/tank/harvester things - - which is what they'd need to get the job done, right? So that would happen pretty quickly, right? Like, suddenly, spaceships start landing, the hatches open, and out come these killer shredder robot tractor/tank/harvester things mowing us down like action figures accidentally left in the grass before lawn mowing time (which actually happened to me...my Bionic Man doll/action figure guy...long story). Anyway, it would happen REALLY FAST.
If they were coming here on a goodwill mission, I still think it would be different than a big swirly thing in the sky. If they're advanced enough to get here, they're advanced enough to understand us very well, I would think. I do think that they would contact our leaders first. There's a chance that they would disagree with our leaders. (Imagine that: somebody disagreeing with our leaders.) Maybe the aliens would decide to overrule the decisions of our leaders to "repress this information because of the tremendous shock that it would cause" - because they think that we the people can actually handle it...or for whatever reason. Even if the aliens decided to ignore our leaders and reveal themselves to us, I still don't think they would do it with a gigantic swirly thing in the sky.
How would they reveal themselves to us? I don't know. Ask a scientist. Maybe they'd send out a bulk email...which might would end up in the spam folder of our email accounts...and who uses email anymore...Twitter? Facebook? Both? TV?
I don't know: I just don't think that they would freak us out and give us heart attacks with some grand entrance...if they meant us no harm, I mean.
But, let's look at the other side of the argument, and can a better argument be made against all the nonsense I just typed here...: Why would aliens create a gigantic swirly light display in the sky prior to their arrival? ...or not even prior to an arrival...maybe they just did it to do it...space performance art...space graffiti... Maybe aliens are a bunch of artist types.
Maybe it would be a good way to introduce us to the idea that there is some kind of activity in space which is the result of _________ something, what...aliens...possibly... You got people around you, some of them believe this is alien activity, and they are going around saying it. So the idea is being placed in our heads, the possibility, whether we believe it at this point or not. Maybe more 'signs' will be presented. And bit by bit, the bigger picture is pieced together: there are aliens. They are dropping hints of their existence in the sky. Little by little. Some people swear that they've seen them. Everybody you talk to has a story about some weird moving light they saw in the sky (I do. My wife and I were laying on our backs one time in Cape Hateras, North Carolina on a camping trip on time, and we saw a bunch of lights circling in the sky and zig zagging and all that...I asked her if she saw it, and she said yes, and we corroborated and described and matched our descriptions and we both know and remember what we saw)...
...where was I going with this...I don't know
Maybe my tiny little brain can't understand why aliens would come. Maybe there are infinite reasons to come here, and therefore, there are infinite ways they'd make their entrance.
Why not a grand entrance? Why not pomp, grandiosity...if they're advanced enough to get here, maybe they have some pretty big egos.
I definitely don't think that this was the contact, but who knows - - maybe it was the beginning of a series of introductory hints before the big contact.
Maybe there's some alien kid, from some supremely advanced space world in the sky - the kid is bored - so he just lit off a firework in the sky in front of a bunch of primitive creatures just for kicks - in his little space aquarium in his room.
