What Is the Heliocentric Theory?

The heliocentric theory is like saying the sun is in charge of the whole dance, and Earth is just one of the dancers. Before this idea, everyone thought Earth was the center of everything, but now we know that the sun is actually at the middle, with Earth going around it like a planet on a spinning carousel.

Examples

Imagine Earth as a kid on a merry-go-round, the sun is in the middle, and you're spinning around it.
If you live in a house and the sun is outside shining on your roof, that's like the heliocentric theory, the sun is the main thing, and everything else moves around it.
The moon goes around Earth, and Earth goes around the sun, just like how one person can go around another in a circle.
