Okay, kiddo, imagine if there was a really important superhero who had the power to control life, death, and then come back to life again (like a video game!). Some people believe in gods and goddesses who can do this. These gods and goddesses are called life-death-rebirth deities.
Basically, they can bring living things back to life, decide when it's time for them to die, and then make them come back again. It's kind of like a circle - life, death, rebirth, then repeat. These deities are usually associated with different mythologies or religions around the world, and they often represent different things, like change, balance, or renewal.
So, when people talk about life-death-rebirth deities, they're talking about these powerful beings who can control life and death. Even though they might seem a little scary or mysterious, they're actually seen as really important and special to many cultures.
