They've spotted the first type* of molecule, no? Not the actual first molecule.

  They're all interchangeable, right? Unless the first compound was really, for some reason, between a deuterium and an H3. But the difference in energy levels would be hard to detect. In any case, the scarcity of signatures outside violent environments indicates that no primordial HeH compounds survived, and these are recent re-occurrences. So, "the first type of compound". Less punchy, I guess.

    >They're all interchangeable, right? Only with respect to use (properties). They still all have different histories (space/time lines). If they indeed have found the first molecule, that would be a huge thing (and a huge mystery, of how they've managed to (a) find it, (b) recognize it as such, since all are interchangeable).
