Hah, maybe. And maybe we die every night when we go to sleep and are only deluding ourselves into thinking we're the same person who went to sleep. But ultimately "dead" is a matter for us living beings to define, the universe itself has no notion of elan vital that discriminates between the living and the dead.
A useful thought experiment is to consider a machine that first duplicates a person and then drops the original into a meat grinder.
The duplicate that steps out would be identical to the original and have no memory of having been ground.
Would you step into such a machine, safe in the knowledge that from the point of view of the universe and all other living beings, you would emerge unharmed?
Well, there'd be two consciousnesses produced both of which I'd think of as me, pre-duplication. And one would die in horrible pain. I'd really rather not die in horrible pain even if there was still a me around afterward, though you could probably offer a large enough inducement that I'd take it. Of course, there exist inducements that would get me to consent to the meat grinder without duplication
Hugh Jackman does, in the film "The Prestige" - https://www.imdb.com/title/tt0482571/ - with the inducement being "to perform the greatest magic trick" and one-up Christian Bale.
