To answer this question, only one fact and one piece of logic are enough.
You know Li Bai and know at least one poem written by him, then this indicates that this person once existed, but you did not exist at that time.
When you mentioned Li Bai, were you surprised to find that many people knew and knew a certain poem he wrote?
Obviously, Li Bai’s existence is not transferred by your feelings. Similarly, your existence will not disappear just because a netizen hangs up and loses consciousness.
The last poem sent to Li Bai:
People today cannot see the moon in ancient times, but this month once illuminated the ancients. People in ancient times and today are like water flowing, and it is the same when they look at the bright moon.
I hope it can help you think more deeply about the universe! ^_^
