This has definitely gone very off topic. Remember please that this was about Hawking making a claim about UFO's not being alien spacecrafts, now we've got pictures of "aliens" in the thread and people arguing over what to believe.
One simple point for the "aliens exist" camp, they tend to believe that the "Military Government Elitists" are keeping everything hidden, however how many countries are on this planet of ours?, how many of those countries would love to undermine the secrecy of another country by bringing to light something that was "buried"? (too many to mention) There is no way the entire worlds governments could agree to keep aliens a secret, they can't even agree on what actions to take when one or other country plays up.
So please get a grip with reality and don't let all your grey matter (not aliens but that brain tissue you have) concentrate on things of no material value (unless of course you are doing a Phd in Philosophy then by all means talk about non-material things all you like)
