It's just that they had to wait millions of years. For the player character it's a total coincidence they were born near the supernova time and saw the statue 22 minutes before, which adds to the overall theme of being totally unimportant but also the most important piece of the puzzle.
Don't read this KP (it's probably fine actually, I think you know it all already but just in case):
I just think "the whole universe is way older than we thought it was and we just missed that all of it is dying, coincidentally right now" is like. Nonsense. Thematically it's fine. As the solution to a big mystery you spent most of the game trying to figure out I thought it was extremely unsatisfying, especially considering that every other mystery in the game has an answer that I find very clever and fitting. To be clear I'd have been fine with "this one specific star just happens to be dying right now". I don't think that twist scales up very well though.
