... at least the Russians have released some of their "unexplained" sitings over the years.
One thing that bugs me is whenever someone mentions UFO's everyone just goes
"little green men from mars lolz" 
. I believe that is a very naive perspective on the universe. The sheer size of the universe is so impossibly huge that we can not even begin to attempt to comprehend its scale. We are one solar system, in one galaxy... which in itself has billions of star systems, which is just one galaxy amongst millions if not billions of galaxies...
And we are to believe that we are the only example of intelligent life? We are a very young species, there is nothing to say that in the long life of the universe there isn't a species or many species that may have cracked quantum physics and created machines capable of bridging the immense distances between the stars. Wormholes/Warp drive are all sound theories, we just don't have the technical prowess or knowledge to create them... perhaps somone out there has?
One thing that would puzzle me, is why would such an advanced race even want to come to this backwater planet (if they have)? We are pretty barbaric still, killing each other for petty little things like money or power.. we can't even mix with each other properly because we believe in make-belief God's or don't like the colour of their skin, whilst killing the very planet we live on because it would "cost" too much to impliment the drastic changes to our economies and lifestyles...
We have quite a way to go before I think someone would stop and take notice of us...
PS: And before anyone asks, there are no green men on Mars... its a dead world the only chance of finding life would be frozen bacteria in the polar regions.
