There’s many people who want very much to find life on Titan, because Titan is covered with oceans of methane... a “fossil” fuel. If they don’t find life there then people might claim that fossil fuels on Earth aren’t from fossils. With lefties, it’s follow the money, the control, or the stupid. It’s one or another.
Methane is not considered a fossil fuel. It is the simplest organic compound, and was proven to be produced through biological and non-biological process in the 18th century.
We need to give these scientists credit. They did the opposite of what the global warming con-artists do. They had a hypothesis of how an alternate biological process would work. They projected what it would look like if the processes were running on the moon. Then they looked to see if the evidence was there. (Actually, they tried to disprove the theory ... that’s the way the scientific method is applied.)
They also admit this doesn’t prove the theory. The only thing they can do at this stage is disprove the theory.
