why couldnt we simulate all the events on earth with some amount of computing the universe holds? couldnt we simplify things and use heuristics and working models to recreate our world and resurrect everything that's ever lived?

the only issue i see is stars that are gone, space objects that impact earth, but those are miniscule when the computing gets to the point that it can simulate life again.

if it's all deterministic then why couldnt we figure it out?
