Well. You see.
The sun is the most massive thing in nearby space. we're flying around it fast enough that it's gravity- a result of all that mass- isn't able to drag us in. this is called an 'orbit'. The Earth, is orbiting the Sun and has been for a very, very long time. we call a single orbit a 'year'.
Now, while the Earth is orbiting the Sun, and we're all doing stupid human tricks, the Earth is also spinning like a top. This rotation is what causes our day and night cycles. As we stand on a single place on the Earth, it looks like the sun is travelling across our sky because we're spinning around.
It's like being on a Carousel going round and round. As you go around, you can see people in line waiting to get on, and then you go past, and you can't see them any more. and then you come back around and you see them again.
