Methane Lakes and Methane Rain on Titan: What it All Means

 

 

Water profoundly affects Earth’s climate, weather systems, surface geology and tectonics. Substitute the word “Titan” for “Earth” and “methane” for “water, and you have a relationship that is equally profound.

That makes Titan more an analog for Earth’s future tha for its pre-biotic past.0
