Actually, to me, this seems like a perfect situation to apply Bayesian inference: we need to update the probability estimate of a hypothesis (there is life in outer space) based on new evidence (they found those particles through their experiment).

Anyway, I completely agree with your last sentence: It's certainly a good thing to investigate, I'm not saying they're charlatans. It's the "very likely" that I didn't agree with :)
