In a heliocentric system, earth revolves around the sun.
I'm thinking true heres why lets say you have a bird and the bird eats worms.. and all the worms in the world are gone the bird will die and what ever animal ate that bird will die and what ever animal ate that bird will die and so on

it is built on years and years of scientists figuring things out, countless expirments, inventions. etc.
hope this helps.
