Billy Graham, for example, has stated that it's likely there are other life forms out there. His take on it is that we should regard them as children of God, even as humanity is. The Vatican came out with a similar statement three or four years ago. Where you're going to have a problem is with your really orthodox groups, people who think the Earth is only 6,000 years old. They are going to see this as a threat to their very literalistic doctrines. It's been by turns frustrating and fascinating and wonderful beyond imagination.

There is a secret government -- a covert government -- operation that has dealt with this for at least 50 years.
