And consider that ETs do not simply want to just say "hi".
When contact is made with a new species, they'll want to have that species be a member of the community, and share and learn and grow with everybody else in a synergistic manner, you know... like a community... in space.
Its our choice, and we can say "we're ready" to join whatever interstellar community there is, which I believe is so much grander than anything we have imagined, by choosing compassion over cruelty. By LIVING compassionately. the first of those space faring people who will build that interstellar community with compassion, making a very cold and hostile universe just a little warmer, and a lot more friendly.

So where're they? They have the means to be here, but aren't.
what makes you so sure?
Shostak also admitted that the discovery reaffirms the idea that life could have emerged in the Galaxy a long time ago. "It's been possible to have worlds with life for quite some time now," he said, "there could be life out there that's billions of years old."
The need for a garbage patrol was clear, and more than one intelligent species had taken the necessary steps. Every robot probe launched by a newly emerging intelligence would be met, sooner rather than later, by an older, more sophisticated probe programmed single-mindedly to destroy any self-replicating machines that didn't have the necessary inhibitions to keep things as they were. "You can look," ran the interstellar dictum in effect, "but you'd better not touch." The Frank Tipler had been caught red handed despoiling a planetary system, and paid the price.
In theory, a self-replicating spacecraft could be sent to a neighbouring star-system, where it would seek out raw materials (extracted from asteroids, moons, gas giants, etc.) to create replicas of itself. These replicas would then be sent out to other star systems. The original "parent" probe could then pursue its primary purpose within the star system. This mission varies widely depending on the variant of self-replicating starship proposed.
Given this pattern, and its similarity to the reproduction patterns of bacteria, it has been pointed out that von Neumann machines might be considered a form of life. In his short story, "Lungfish" (see Examples in fiction below), David Brin touches on this idea, pointing out that self-replicating machines launched by different species might actually compete with one another (in a Darwinistic fashion) for raw material, or even have conflicting missions. Given enough variety of "species" they might even form a type of ecology, or — should they also have a form of artificial intelligence — a society. They may even mutate with untold thousands of "generations".
The first quantitative engineering analysis of such a spacecraft was published in 1980 by Robert Freitas, in which the non-replicating Project Daedalus design was modified to include all subsystems necessary for self-replication. The design's strategy was to use the probe to deliver a "seed" factory with a mass of about 443 tons to a distant site, have the seed factory replicate many copies of itself there to increase its total manufacturing capacity, over a 500 year period, and then use the resulting automated industrial complex to construct more probes with a single seed factory on board each.
It has been theorized that a self-replicating starship utilizing relatively conventional theoretical methods of interstellar travel (i.e., no exotic faster-than-light propulsion such as "warp drive", and speeds limited to an "average cruising speed" of 0.1c.) could spread throughout a galaxy the size of the Milky Way in as little as half a million years.[
A response came from Carl Sagan and William Newman. Now known as Sagan's Response, it pointed out that in fact Tipler had underestimated the rate of replication, and that von Neumann probes should have already started to consume most of the mass in the galaxy. Any intelligent race would therefore, Sagan and Newman reasoned, not design von Neumann probes in the first place, and would try to destroy any von Neumann probes found as soon as they were detected. As Robert Freitas has pointed out the assumed capacity of von Neumann probes described by both sides of the debate are unlikely in reality, and more modestly reproducing systems are unlikely to be observable in their effects on our Solar System or the Galaxy as a whole.

more likely than no it is more like my way because the other way doesn't make sense and is highly unlikely.
maybe you are looking at this the wrong way?
Why are we not ready? The better question is in this tiny picture of the Universe. Is it plausible that in the vastness of the Universe, they just haven't found us? (even if intelligent et exists)
You see a tiny glimpse of billions upon billions of stars with as many or more planets. We have no idea where or if the Universe ends or even where its' center is.
Now, Earth is just a very tiny, tiny, blue dot somewhere out there in the vastness of this universe.
Point, if ET even does exist (Intelligent ET), then there exists trillions of reasons why they have not found us or have even cared to find us.
The picture above is Disclosure! It discloses that earth is just a tiny grain of sand sitting in the Sahara Desert. If found, it will be by pure luck. Disclosure is our responsibilty of finding them......Earth is approximately 4.5 billion years old. I wouldn't count on it anytime soon.

I don't think the planet can take much more of us for much longer.
OMG, it's either YOUR way or someone else's opinion is unlikely or they are looking at it wrong??? If you think intelligent ET has already been here....fine and dandy.
Is there some type of life out in the vastness of this Universe? The odds are extremely high that it does, but more likely to be microbial than anything else.
Read this for a review of what I've described in my last two posts.
en.wikipedia.org - Self-replicating spacecraft...
SO I do feel they've visited, but I don't know in what capacity. Nor do I know the purpose of their visitation. I hope it's not to put us on a menu.
Why would you think that? if there are planets billions of years older than ours and life somehow sprang up on it before it was even cooled, then why would it be so unlikely that same "random" event wouldn't happen somewhere else and give rise to beings that had a need to explore the universe too? There is already us as an example that it does happen so what would be preventing it from happening elsewhere? I don't get it it just sounds like you are saying that because you don't want to think any other way. It's not my desire to make you think what I think, but you're going to have to accept it one way or another because it's right around the corner.

We are so far from ready, its not even funny.
What if aliens came to earth many years ago....
then simply egineered us humans from a hybridisation program
Then fed us a set of rules, gave us basic knowledge and left us to fend for ourselfs.
this would explain why there was so much worship and talk about angels and gods in the ancient times
and would also explain why they don't show themselves again, they already did, and that reason was just to kickstart our race.
and now they simply come and go, watching their creations unfold.....
i acutally like this theory, maybe they have done this thousands of times before all throughout the universe, and their end goal is to create more and more intelligent speciesedit on 14-12-2013 by SkuzzleButt because: (no reason given)
