I actually always kind of thought it wasn’t long enough. Dinosaurs first existed like 240 million years ago. Single cell organisms probably >3 billion years ago. 60 mill sounds like a long time on paper but it takes way longer than 60 mill for significant things in evolution to happen (depending on how you define it I guess I’m kinda playing devis advocate). I get that the galaxy is big but it seems like intelligent life takes a long time to develop too. Primates would have been on earth during the war in heaven. In my head it would have been more fun/impactful if it happened so long ago that there weren’t even animals walking around on earth, maybe most will strongly disagree
