There is no doubt in my mind that aliens exist.
There is no doubt in my mind that we’ll never see them
I think a small amount of doubt is required here.
I wasn’t talking about your mind.
The numbers are incomprehensibly large. It’s not just implausible that we’re the only planet in the universe with life, it is as close to impossible as makes no odds. The only problem is that they will be a very, very, very long way away.
It’s not dissimilar to the Atheist argument. I cannot disprove the existence of a god or gods, but I can say beyond any reasonable doubt that man created god in his own image rather than (as is often asserted) the other way around.
I don’t know any of these things of course, and cannot. No-one can. But the balance of probability is astonishingly high.
TL;DR: Aliens exist. Aliens are not in our airspace nor in a secret bunker in Nevada. God isn’t real. Thank you for coming to my TED Talk, I’m here all week. 🙂
