Religious beliefs aside, how do you know "we" haven't already? Governments of the world would likely want to avoid mass hysteria and keep it hidden. We have had many people in high ranking military/civilian positions come toward with their experiences. I'm not usually one for conspiracy theories, but it comes to a point when so many people come forward, you have to ask yourself, are they ALL liars? Sightings/ reports of abductions have done nothing but increase as the years go by. Are they all fraudulent? I'm sure the majority are, however it is of my belief that more then a few aren't.
