Yes. No wonder the government released it all, have you read the letters the morons wrote to the government? Most are like "LOL I saw a ufo at 11am on a saturday whilst in ASDA car park, but there were no other witnesses".
When most people hear UFO, they automatically think "Aliens". I am sure there are lots of UFO's sighted, but there is no way any of them are from another planet or of alien origin. They will just be top secret experiments.
The way I see it, if we are here there is no reason why there are not other intelligent beings in the trillions upon trillions of other solar systems, to think we are alone is rather naive.
Whether we get visited by them is another matter entirely but if they have been in existence for far longer than us then who knows? Look how far we have come in the last 100 years. The crazies deter real scientific research into though.
