Yes, I think that alternate histories are more the domain of Infinite Histories. But as you said, an alternate history is still advisable in this case to prevent the setting from being invalidated by the relentless march of time.

If this was to become something unique to Galactic Crucibles (which I don't personally think is necessary), it could be turned into an alternate history which involves humanity interacting with the wider universe some time in the recent past, such as District 9. (or the far past, if you want to involve some sort of alien-conspiracy-thing like Prometheus).
