ELI5: What is a P-Zombie?
gpt
When you look at the behavior of a person or talk to them, they will seem like they are alive the same way as you are. They see colors, smell the spring air, know that they are there. They think therefore they are, right?

However, you can't really see into their minds, can you? The idea of a P-Zombie is that maybe such people aren't really sentient, they just behave exactly like the people who are. They don't experience being tickled like you do, but they react as if they did. They don't feel sadness when someone they like dies (and they also don't actually like them), but they behave just as if they did. They could be a robot for all we know, or a human body without a "soul" (however you define that) and so on.

As long as it isn't conscious and doesn't really experience qualia but from the outside is indistinguishable from someone who does, it's a p-zombie.
