Imagine that the year is 2045, and scientists have just discovered an extra-solar planet, roughly the same size as Earth, and its atmosphere contains all the signs of life, O2, O3, and CH4, and etc. But that's not all, the scientists are up to another shocking discovery, they have also detected the trace of a chemical called Chlorofluorocarbon, or CFC, a sign of the planet having an industrial pollution which is a sign of technology. As it happens, astronomers around the world, quickly swing their telescopes towards that planet in hopes of being the first one to capture an alien transmission. Then, a group of astronomers in the California's desert have finally detect an anomaly through the vacuum of space, they have finally detected the what might seem like an alien transmission from that planet. But that transmission does not make any sense to anybody. It's the same as we didn't know what the Egyptian hieroglyphics meant for a very long time until people have managed to decipher them. The same principle applies here. And even though as scientists won't be able to translate and decipher those alien signals, that would still be the greatest scientific discovery of all times, it would finally prove that we are not alone in the universe. But there's another problem, and that is, what to do next? If I would have to make a decision, I would keep those news quiet, instead of letting the entire world know about it. The thing is, who will be in charge for making decisions in that case? Should we transmit a signal back to them (it could be done by beaming up laser signal containing all of our information), but wouldn't doing so be an extremely foolish thing to do? What I mean is that, we have just discovered another intelligent life, and we have no experience in that field. That is to say, we would not not whether those extraterrestrials are friendly or not. And even though it is unlikely that those extraterrestrials would be able to get to us (it would normally take an estimated of a thousand years), it might be possible that those extraterrestrials have exited for much longer than we humans have, and so they might be able to travel at the speed of light and actually reach us in about twenty years. But there's another problem, if everybody would find out about that discovery, first of all, many will freak out, panic, while others will be extremely happy. Next, there will be freaks who will try to send or beam up unauthorized signals to that planet, and as the result of that, what would happen if twenty years later, our telescopes detect a fast moving object, who's shape is too smooth and accurate to be an asteroid, and that is heading directly towards Earth. As it comes closer, it is clear that that is an alien spaceship. As it approaches our planet's atmosphere, it splits into two and each settles into position above each pole. Panic spreads, as spaceships appear at equal distant points around the globe. So, are they here to crush us, or like us, are they driven by the quest for knowledge, to meet a new neighbor?

Sounds like a treatment for a sci-fi movie script.  Flesh it out with some character outlines, a little inter-person dynamics (former lovers or rival investigators, a government cover-up hit squad), some wild chases, explosions, media hype, mass panics, that stuff puts butts into seats.
The big numbers come from 3D films by major producers, award winning or track proven directors.
If you do anything with Hollywood, first get a bullet-proof copyright, an agent, and network with some knowledgeable insiders.  See the movie "Get Shorty" for a good idea of what you are facing.

We do not know if they are freindly, or even exist. there may be alien bodies in a secret base called Area 51. No one is aloud in, except the military. They do many experiments, and may have alien bodies and alien spaceships in there. No one really knows if they are real...

Well you're assuming that it matters whether they are friendly or not.  If their knowledge is the same as ours (as indicated by the CFCs in their atmosphere) then they don't have interstellar space travel.  As you point out, at conventional space speeds, it would take 10,000 years for a satellite launched today to make it to the nearest stars in our neighborhood.  So we couldn't attack them and they couldn't attack us.  Aliens would similarly not know the state of our weapons development.  Either way, the effort needed to launch an invasion force is quite different from the effort needed to launch an exploration probe.

Much also depends on how far away the star is.  Let us say it is 1,000 light years.  That means the information we are getting is 1,000 years old.  The planet in question might have already self-destructed.  If the planet is very very close, say 5 light years, then we might actually be able to signal one another without too many delays.

Judging from the skepticism about the moon landings one sees on these groups, about 85% of the world would assume that the whole thing was a hoax.  After all, the unintelligible signals could be coming from anywhere, maybe a NASA plot.  And who would believe a bunch of scientists waving around spectrographic evidence of CFCs?  

If on the other hand they transmitted something useful to us, like plans on how to build a faster-than-light spaceship or something similar, that would definitely change things.  

It is likely that an advanced civilization that was actively transmitting to us would give considerable thought to the problem of decoding.  On the other hand, our transmission technologies are barely a century old and have already changed from analog to digital format, and may change again.  Perhaps we haven't stumbled upon the "obvious way to communicate in Interstellar space" yet.  If you take the history of complex life on Earth as roughly 500 million years, and that we've had serious astronomy (for this kind of speculation) for about 100 years, then there is only a .0000002% chance that an oxygen atmosphere will also indicate an advanced civilization.  

But I like the ideas.  Remember that in "Independence Day" (the movie) the intentions of the alien ships were unknown at first, just like you say.  The lesser known movie  "Contact" (1997) with Jodie Foster goes into a great deal about the social reaction and the politics that would occur with such a contact; so does the famous sci fi classic, "The Day the Earth Stood Still" (1951) (try the youtube link below).

One thing, it will take a new generation of telescopes to detect oxygen atmospheres so it won't be "telescopes around the world."  It might be the VLT or OWL telescopes that are currently planned and likely to be built.  But there won't be more than one or two up to the job.  I don't know about detecting an incoming space ship.  On the one hand, it might come in smoothly.  On the other hand, if it is braking from relativistic speeds it might actually be firing reverse thrusters for some time before it approaches our solar system.  But coming in at the speed of light is going to take some significant braking or reverse thrusting in order to avoid shooting right past the solar system.
