Being omniscient and familiar with astrophysics (dude did whip up an entire planet and ecosystem in under a week), Y-man knew they were never going to make it past 40k feet let alone the fucking Kármán line, but dude still had a shitfit and crashed out, ostensibly creating (at least the genesis of) the earth’s languages, but more pointedly tried to stop the people from doing what he already knew they’d never be able to accomplish.

Got it.
