Right, Russia, China, and the US are collaborating on anti-gravity technology...the idea that life could be out there, sure. The idea that those three nations would share cutting edge military applicable technology, not buying it.
Many of the things we take for granted every day is either made in China, Japan, the US, Canada, or all of the above.
As for working on top secret things together?
Not too hard to believe. The International Space Station is indeed "International" in regards to who operates it, as well as the various parts it was built from.
There is a common goal between nations in regards to working on space technology to lead up to space travel. The whole Gene Roddenberry concept of a unified Earth isn't so far fetched when you think of it. If humans can locate other planets to live on or to obtain resources needed for humanity, many of the current global conflicts over oil and other resources would not be necessary, especially if we can make the trips to each planet in an hour or two.
It is necessary for the survival of humanity to eventually find other planets to live on and as it currently stands, humanity has all its eggs in one basket.
Many skeptics claim that while they believe Aliens do exist out there in the vast Universe and even our Galaxy, they also believe that the chances of aliens visiting our planet are next to zero.... but why is that?
Simply based on the mathematical numbers of chance?
Because we're not that interesting?
We have technology and various energy waves emanating from this planet every single second and radio waves which have been emitting from the planet since the 1930's..... We've got plenty of activity on this planet to hit the scanners of any possible ship out there, regardless of how far away (considering space traveling ships would have superior sensors and technology on them than what we currently have) and I imagine we'd be a bit more interesting that some single celled organisms swimming around in a pond of goo.
If aliens had the ability to travel through space, they'd have no interest in primitive man.
It's nice and safe to think that isn't it?
If we could travel to other planets, do you think we'd not be interested in whatever was on those planets?
Hell, we're currently digging through Mars looking for any evidence of plain old water.... if humans found one single micro bacteria on Mars, the whole of humanity would simultaneously jizz their pants.
To think intelligent life able to create space ships and travel to other planets wouldn't have the slightest interest in Earth or any life on it is naive.
I'm not saying aliens out there are actively looking for us and our planet in particular because we're so special, but if any did come across our planet, I'm more than sure they would at least stop and see what's going on.
