Aliens Don't Exist

And this video goes into the reasons why. And no, the argument that "the universe is just SO big, so there have to be aliens out there somewhere", just doesn't work, because although a huge universe is a necessary condition for life to develop on some planet somewhere, it isn't on its own sufficient; more requirements need to be met (like the right type of star).

Argument from incredulity, a common mistake that people make in this debate.
Yes, he's right about the abundance of chemical elements that would have to go into the formation of any form of life that we'd recognise as such, and I'd also bet there are microbial aliens out there somewhere, but...
Advanced aliens? Nope. Are you familiar with the concept of "Great Filters"?

I don't accept that either; the belief that we're not important in the grand scheme of things, and simply because of our relative physical location (in this case, our distance from the centre of the galaxy). Location doesn't determine worth.
