[Alneyan]

Well, the answer to whether alien life exists or not is quite obvious: just look at Fyron and Narf! Fyron is a proven Vorlon, and have you ever seen sapient mice wielding six-foot tall hammers? Of course not; besides, mice are the true rulers of the universe, and do not hail from Earth.

(What I am really wondering about is how those other lifeforms would think, but that would be another matter, and a bigger can of worms so I will stay quiet. See, you aren't even reading this message!)
