Sure blame the smokers. We are truely evil people!!

"But this would only be possible if there's an ocean underneath the surface that the entire crust floats on top of."

Elsewhere it is claimed that also different explanations do exist for the shifting of the surface. It is also not clear how such a liquid layer could have developed between a solid core and a solid crust.

One can also claim that "it's awfully naiive to say that life can't exist on the sun because it's too hot or because it's too near at the sun."

We also could establish a new religion in which life on Titan is responsible for good and evil here on earth.

I think it's safe to say 50% because we don't know enough to give either side of the argument an advantage.

You know that normally I'd agree with you Jimmy. But as we have yet to discover any terrestrial life form that can survive Titan's surface temperature of about 94 K (−179 °C, or −290 °F), not even extremophils that you refer to; I'd still place the chances of life on Titan at 0%. It’s simply too far away from the sun.

That’s not to say that in the next 10 billion years or so, life won’t spark off as it did on Earth though…

"…in other news, the peace conference between the Titanians and Earth ended in disaster as the volatile atmospheres mixed and exploded. Authorities believe that a cigarette was the likely culprit. No word from the Titanian government as of yet…"

Life on Titan is no less possible than life in a geothermal vent. Before that came out, I'd have laughed at microbes in boiling poisonous gas venting from the bottom of the ocean. I'll say 7%.

Life on Titan surface 0% (way too cold for life)
Subterranean life on Titan 0% (way too cold for life)

Consider that Ethanol and Methanol (if located on the surface; located underground too) are active ingredients in antifreeze, so a subterranean liquid water suspension is no surprise. (possible gravitational/thermal tidal heating)

Basically, Titan is too cold above and below ground. If you consider that Ammonia (NH3) boils at -33.34°C (239.81 K) we know the subterranean temperature on Titan is below -33°C for Ammonia to be present as a liquid.

Your Freudian slip however, might induce deeper discussion:
Terrestrial microbial life on Huygens (now on Titan) – Have we contaminated Titan for the distant future?

as for the possibility of life, i'd give it about 2%, but that's a better cahnce than i would have given it before reading this article.
