Is there a specific word that means something that was always there, as in the first thing to be created and the last thing to cease to exist? Like the "Alpha and Omega" concept but in one single word? As in, what would be called the very first atom to come into existence on this universe if that was the very same atom that will be the last to decay when this universe ceases to exist.

Consider eternal. Something that is eternal has always and will ever be. Therefore it must have been first and will of necessity be last. Of course, given eternality, beginning and end don't really have any meaning.
If you're dealing with processes, you might take a page from programming and refer to the process container which starts before anything inside it does and finishes after all its contents do.
Took a bit of abstract thinking - (imposed) boundaries and borders either for the purpose of just existing, or breaking/crossing them, are always present. "Space: The final frontier"?
Extremes, endpoints, bookends don't carry the same implicit need/intent of breakableness(wouldn't use fragile in this case).
In all honesty, i reckon there's naught a most expressive, specific word for what you seek - correct me if I'm wrong.
