Nobody was saying that.

What their saying is that C (Methane) is usually only formed by either A (life) or B (geology). Hence if C is present it is VERY VERY likely that either A or B is.

Neither of witch were thought to be particularly exciting on mars. So either way it's big news.

That and the fact that something was replenishing the methane.
I would agree with you there. Sorry, it seemed that Charles suggest If A then B, B therefore A in his response to BlackTiger. My apologies if that wasn't the case.
