Okay, so you know how humans are people like you and me, right? And we have bodies that need food and water to stay alive, and we can think and talk and do all sorts of things like play, learn, laugh, and explore?
Well, zombies are different. They used to be humans, just like you and me, but then something really bad happened. There was this virus or disease that spread through the world, and when people got infected with it, they turned into zombies.
Zombies are kind of like robots that behave on their own. They don't need food or water or sleep or anything, but they still move around and try to find other people to infect and turn into more zombies. They don't think or talk or do anything except try to eat human brains.
So, when you hear about humans vs. zombies, it usually means that there's a story or game or movie where a group of humans has to fight against a bunch of zombies. The humans have to be careful and smart, because if a zombie bites them, they might turn into a zombie too.
The humans might have weapons like guns, knives, or baseball bats to defend themselves, and they might try to find a safe place to hide, like a fortress or a bunker. They might have to work together and come up with a plan to defeat the zombies, like finding a cure for the virus or destroying the source of the infection.
It can be really scary to think about zombies, because they're not like any other creatures we know in real life. But it's also kind of fun to imagine what it would be like if we had to survive in a world full of zombies. Would you be brave enough to fight them? Would you be smart enough to stay alive? It's up to you to decide!
