Life on Titan?

Two new papers have come out, suggesing that there could be life on Titan that "breathes hydrogen, eats acetylene and excretes methylene". But, as Maggie Korth-Baker puts it on boingboing:

let's knock out one basic thing right off the bat: Nobody has discovered alien life. We have not found E.T. This is only a test of the emergency high-pitched happy squealing system.

That said, it probably wouldn't be remiss to clap your hands delightedly, like a little girl. As I said, nobody has found alien life, but they did find the sort of evidence that might suggest alien life is down there on the surface of Titan, waiting to be found. It's a little like walking up to a house and finding the front door open, and, inside, a T.V. stand that's missing a T.V. It's reasonable to assume the house might have been burglarized, but there are also other plausible explanations and you don't have enough evidence to know one way or the other.
