Another Earth in Our Mantle
Scientists researching the Earth’s mantle have discovered what they believe to be a vast body of water three times the volume of all of our oceans combined, contained within a mineral layer 400 miles inside the Earth. Since we have not drilled down far enough to confirm these findings, could we be wrong about our planet’s composition? Enter the alien astronaut theorists who claim that according to our earliest methodologies, another Earth may not be found in the heavens but deep within our own planet, which also gives credence to the Hollow Earth theory. Tune in as The History Channel unravels this mystery.
