For Nothing All Shall Go

There's the intrinsic simplicity

     Of interpreting language, now that
All languages are dead. Let's suppose

That these creatures, despite a broad range
     Across available habitats
On their watery planet, kept close

In time across archipelagos
     Of extra-aqueous atmosphere,
And therefore diverged very little.

As evidence, one could consider
     Either the fact that all their grammars,
Insofar as known at extinction,

Score so near equivalently
     On mean complexity, they're the same,
Or one could contemplate the planet's

Surviving, systemic, nucleic,
     And, so far as we yet know, unique
Codes for information relevant

To replication and take notice
     Of by what minuscule differences
The furthest removed of these creatures

Diverged from even their close cousins.
     Either way, any one ever lived
Among these fascinating beings,

Among we exozoologists,
     Was pretty much the same thing speaking
The same primitive glossolalia.
