Reply #21: It's also a good cop-out

Other dimensions? Give me a break! It sounds good, especially when you bring up the physical impracticality of interstellar travel. Claiming that alien life might exist on other dimensions might sound convincing to someone who doesn't really know much about quantum physics. But when physicists talk about "higher dimensions" that exist in our universe, they're talking about dimensions that exist on a sub-atomic scale. Sorry to burst the sci-fi bubble.

There is NO evidence of alien visitation whatsoever. All these people who claim to have been implanted with alien devices? Where are these alien implants? Don't you think that even if ONE of these idiots were able to produce a verifiable alien artifact from their body, we would know about it? Where is the physical evidence of aliens? Oh that's right - the military somehow always manages to get to the crash scenes before everyone else, scurry away all the evidence, and keep it secret.

Sorry, but I'm not buying into all this alien hogwash. Sure, I believe that there are advanced alien civilizations throughout the universe. But they're likely keeping to themselves, confined to their immediate "neighborhood."
