Gehenna

Gehenna is a place that some people believe exists in the afterlife. It is often described as a very bad and scary place where people go after they die if they have done really bad things in their life and haven't asked for forgiveness. It's like a type of punishment for them. In some religions, people believe that there is a big fire in Gehenna that burns forever and ever, and that it's a place where people will be tortured and suffer.

But it's important to remember that not everyone believes in Gehenna, and some people have different ideas about what happens after we die. Some people think that after we die, we are just in a state of rest and peace, while others believe that we are reincarnated and come back as a different person or animal. It all depends on what each person believes and how they understand the world around them.
