A subject that has always fascinated me. I don't think there will any earth shattering news (excuse the pun) I think governments all over the world know more than they let on if intelligent life exists. It will be the usuall cover up if there is any truth. Can you imagine the scientific and religious consequences if they say " yes intelligent alien life forms exists and they have been visiting earth for many years " I can't honestly see that happening . There is a programme on BBC 2 tonight 9pm by Brian Cox that may well shed some light on the subject.
I've always been fascinated by extra terrestrial life too and like you say even if we have been visited or had some sort of sign of intelligent life then the information will only be drip fed to the public to avoid mass panic.
That said it could be a good time to buy shares in gun and ammo makers as you know how the Yanks love to panic buy that shit whenever anything happens

Aren't there more stars out there than there are grains of sand on earth and almost all stars they have looked at have planetary systems, to me it's unthinkable that somewhere life hasn't started elsewhere.
Some will be microbial and some far more advanced than us, whether we have been visited I have no idea and I don't buy all this shape shifter shit the likes of David Icke puts out.
Most of the UFO sightings can be explained by weather phenomenon etc but there are some which are just plain weird like when things appear on radar and change direction by 90 degrees at Mach 2 etc

Part of the problem is that pilots etc don't report things they see as historically it spelt an end to their career, they need to start having an open mind about this stuff and gather information from people who are seeing this stuff 1st hand
