      The world will eventually end when the Sun expands as it’s life cycle comes to an end. This is a good picture showing the life span of the Sun, so you can see how long the Earth has. By the time the Sun is a Red Giant, it will have swallowed up the Earth.

      However, humans might die out before then due to some other catastrophe like a meteorite hitting the Earth, or some other thing. But it’s very unlikely to happen in your lifetime or mine.

      Just like Sam said, the world will end but we probably have a lot of time left.

      What Sam said. 4 billion years to go pretty much til then, so we have a fair bit of time!
