The Earth core possibly is the antimatter?

Question

The Earth core possibly is the antimatter???

Answer 1

No because when matter and antimatter come into contact they annihilate each other releasing the mass of each as the energy equivalent. If the earth's core was antimatter, the core and the rest of the earth would annihilate shortly after formation.

Answer 2

no anti matter has to be synthasied in nuclear reactors of atom smashing machines
