# But, there is the small matter of all the hills and mountains on the planet and the volume they'd take up.
# So, doing some hand waving and back of the hand calculations I guesstimate that if we take the height of Mt. Everest as 8 kms
# instead of 8.8 kms, it should more than account for the volume taken up by all the hills and mountains on Earth.
