The more we want it to be true, the more careful we have to be. No witness's say-so is good enough. People make mistakes.People play practical jokes.People stretch the truth for money or attention or fame.People occasionally misunderstand what they're seeing.People even see things that aren't there.

There is no deeper religious feeling than the feeling for the natural world. I wouldn't separate the world of nature from the religious instinct...I would not even object to saying that the sense of awe before the grandeur of nature is itself a religious experience.

After the earth dies, some 5 billion years from now, after it's burned to a crisp, or even swallowed by the Sun, there will be other worlds and stars and galaxies coming into being -- and they will know nothing of a place once called Earth.

The chance of receiving a signal from a civilization exactly as advanced as we are should be minuscule. If they were even a little behind us, they would lack the technological capability to communicate with us at all. So the most likely signal would come from a civilization much more advanced.
