Are they among us??

[Waterwolf]

Is there intelligent life on Earth?

[andy hughes]

Well, there's you ..... and me ..... so the answer apears to be 'Yes'.

[dreich]

At one time I would have said yes, but as I grow older I seriously doubt it.

[msminor]

If there is, it's cunningly disguised.

[incitatus]

Yes. Me. The rest of you are figments of my imagination.

Since there's no conclusive evidence, it's strictly a matter of what you want to believe (as in, "Is there a God?").
