Well the galaxy is 100000 light years across. I don't know how old this article is, but it says the furthest planet we've detected so far is 20000 light years away. We're finding new planets all the time, so it could be further now. If a species as primitive as us can see planets that far away, then it wouldn't surprise me if they could detect any planet within our galaxy. We're about 32000 lightyears from the centre of the galaxy. So assuming they are on the opposise side, on the very edge, they'd only need to be able to see about 80000 lightyears, and they'd see our planet as it was 80000 years ago, when it was perfectly capable of supporting life. It's probably more likely that the most advanced aliens would come from planets closer to the middle of the galaxy, as those stars are much older. I just think that if they can see our planet can support life, and if distance is no object to them, then they would have come here.
And I don't necessarily think they would have made contact with us. Maybe they would have no reason to because we have nothing to offer them. Or maybe they have laws that prevent them interfering with the development of primitive species. Or maybe they have laws that say they cant communicate with us unless we are a global government so we can talk back with one voice that represents the whole planet. I don't know, there are lots and lots of reasons why they wouldn't. Or maybe they've tried to, and America tried to shoot them down.
As for detecting their radio signals with our technology, you're assuming their radio signals are even detectable by us. Maybe they transmit them through subspace or something like that.

Presuming exploration craft departed their home systems millions of years ago to ALL stars in the galaxy yes all billions of them, which is easy to occur with millions of years to do it in. Then I'm wondering what probes/craft are already orbiting our sun, but are electronically dead and merely small lumps of interesting artificially made material and design.
With so many rocks out there massive and unknown it would be hard to discover alien craft.
I think it would be worth doing a massive audit of what our solar system contains, and then create a ring of sensors to detect anything that comes in.
The chances us of receiving one of a mass probe programme are quite good. (From not just one alien civilisation but perhaps MILLIONS of alien civilisations, we can rely on others when the previous ones go extinct)
Contact could not be achieved, but a wonderful sign of other intelligent life from long ago would be confirmed.
The good thing about the age of the Galaxy is we don't have to wait on results of our own craft, we can look for others already here or incoming. They may just be token craft just like our voyager witch now is a possible sign for other aliens to pick up on in thousands of years time maybe to a planet like ours and they will think, wow, look at that, and then munch on the grass again after it burns up. But it might miss and go into a lucky orbit of a planet or star sometime, in fact it's more likely it find something than nothing. Eventually a gravity field will control it.
Now if we sent millions of those our of our system, and targeted individually at stars...we can return the favour and keep the ball rolling like those aliens who did the same thousands or millions of years ago.
The other good thing about alien craft is that they hang around once they get caught (unless they burn up, we need a bit of luck...) Unlike radio transmissions which come and go instantly as soon as broadcast ends, such a narrow time frame to witness, hugely more likely to see an alien craft than detect signals I would guess.
But I don't know the odds of safe star orbits. But if they were targeted well in the first place they might have been on course to not be consumed by the Sun or impact Jupiter...

I don't think we'll know (or even have the slightest clue) about intelligent alien forms in the next few decades, perhaps even the next centuries, I mean we don't even have a scalable way of producing energy to ourselves ( I'm looking at you nuclear fusion, we didn't even build a tokamak capable of outputting more energy than it uses ), we don't know with precision, aspects about our own solar system.
That said, I believe that there are currently nice breakthroughs happenning. The next Mars rover ( Curiosity ) for example is a bigger and more capable version of Spirit and Opportunity, acquiring more knowledge about our neighbor planet and even confirming if there was once in a time life in there ( even if primitive or new forms only ) would be a major happening and shed further enlightment on the Alien life discussion as a whole.
Sure, given the scale of Mars' surface, Curiosity has an enormous limitation when it comes to the overall scope of the whole alien life research, however as years and technology goes by ( hopefully, NASA will still be properly funded for the next years ) we can even dream about a powerful rover, capable of collecting and analyzing samples from all over the red planet.
Sorry for the long post, I really am quite enthusiastic about science, even though I'm just an admirer.
EDIT: To be more synthetic: We can't say much today given our current technology stage, but as the Mars' missons go on, many answers and new questions shall pop up. That's the way I would like things to go, that's just one of the many ways NASA is doing. Good job.

I'm more interested about possible life under the surface of Europa, than Mars, TBH. They need to hurry up with that ice drilling mission FFS.

A battle sight on mars sounds more like fantasy. We would have found it by now.

Wasn't there a thing about how bacteria was found on a moon or planet a while ago? I forgot which one it was though.

Someone's been watching too much Transformers
I've read that NASA astronaut Buzz Aldrin played the role of Buzz Aldrin in movie Transformers Dark Side of the Moon. Can anyone confirm this? Supposedly he said that NASA required his and the others' silence back in the day, and that he couldn't now be blamed for not telling the truth back then. Did he say this?

But this was discussed before in length from what I remember.

Dotini without an internet reference link, seems like a try to start rumors?

As far as we know, we're the most advanced civilization in the universe. So there isn't really justification in calling us primitive, though I understand what you're saying.
As for the supposed aliens that can see the galaxy, would they be able or willing to see it all at once? Unless they have an immense lead in physics compared to us, they will see using light of some kind, which would mean that they would be seeing the planet far in the past, which would probably make it harder for them to determine if there is life on the planet.
Those stars are also clumped much closer together and faster moving, bathing everything nearby in radiation and probably tearing orbits apart. There's also a big Black Hole over there.
Unless they had undetectable transmissions from the moment they developed advanced communication, we'd probably see something. It would take years and years for there early communications to reach us most likely.

Okay, I found this: http://www.ufodigest.com/article/transformers-3-silver-screen-saucers-review
"The government’s present-day secrecy on this matter, however, quickly is attributed to the policies of the past as Buzz Aldrin himself – yes, the actual Buzz Aldrin – is ushered into the room and explains to Optimus – and to us in the audience – that “we were sworn to secrecy by our Commander in Chief!” Don’t blame us, and don’t blame the military-intelligence community – blame Nixon!"
Since I don't watch movies such as Transformers, I was curious if any GTP members had seen and remembered this supposed scene from the movie.
As stated in numerous previous posts, my take on "alien" UFO's is that they are natural electromagnetic phenomena, even if they sometimes do seem to exhibit intelligent behavior or take forms which seem to resemble archetypal images familiar to humans. Many GTP forum members seem to agree that organic lifeforms are likely to be found elsewhere in the universe. Since the universe is 99% inhospitable to organic life, it seems logical to me that some of that other 99% of the universe might well be hospitable to self-organizing inorganic lifeforms. This is scientifically possible, as its been attempted in lab experiments. http://iopscience.iop.org/1367-2630/9/8/263/fulltext

I think that considering our planet is at least 200 million years old, and humans have only inhabited it for around a million of those years, it is highly likely that there are civilisations far more advanced. It is impossible to even imagine where the human race will be in another million years. Imagine if another race had a million years of evolution on us.

Sorry if it's the nerd in me but wouldn't it be kinda cool if the Covenant existed? I mean, they will try and kill us, but we will still win in the end I think, unless something happens in Halo 4.
But I don't get why a lot of people are wrapped around the idea that Aliens have to have oxygen and air, what if they don't have to have anything? Just a thought.
