The heat in the Earth's interior comes from the gradual decay of radioactive isotopes, which were present from the moment the Earth formed.
It's called geothermal energy, and is present due to the incredible amount of heat present in Earth's interior from radioactive decay, friction, and residual heat from Earth's formation.
Sunlight is the main source of energy on earth
