The actual earth's mass is massive. Consider land horizontally beyond our technologies reach in every direction. Possibly infinite as they describe space only itss on a horizontal plane from our perspective. Also due to maps by the Buddhist that are from 10000 years ago show that very concept and it shows other holes in the ice where there is a sun and moon and land masses scattered as our continents do. Supporting history on the Great flood that covered the earth and then caused a cooling, winter and the storage of flood waters in the form of ice and water to melt gradually and ve used by the earth and man. This left the earth groaning and travailing in geologic disruption as the forces of water, ice and fire from the grinding tetonic plates and calderasnof volcanos all shaping the earth post flood amd what're live in today is an earth that is still recovering from that flood.
