Still, I have to say that there is absolutely no way you can know this to be true.

1) Physics of space travel - physical barrier of the speed of light (unless you think they can put enough military hardware on enough ships that requires cryogenic sleep to traverse the long distances) makes travel over large disances virtually impossible.

2) Physics of time travel - time's arrow.

3) Physics of cute sci-fi methods - wormholes would be so small and unstable that they would collapse very fast and not be suitable for use even if they exist.

4) Chronology of galactic civilizations - since observational evidence has thus far shown no other evidence for life, it is possible that such life has existed and died, just as our own solar system will billions of years from now.

Thank you for explaining things I already understood. It changes nothing about what I said to andy. I'm certainly no expert in these areas, but I'm hardly ignorant of anything you mentioned. Frankly, it's quite insulting that you would assume I'm uninformed about these subjects.

Ah, of course! I have an open mind, so that clearly means I am a kook. You misundertand me, sir. I'm actually very skeptical. But I'm smart enough to know that I shouldn't dismiss people as crazy simply because they bring up this subject. I'm also smart enough to know that andy can't actually know what he claims to know.

Lastly, I've followed physics, and Hawking in particular, since I was eleven years old.
