Atheists like to claim that there's not enough water on the Earth to flood the whole Earth to the highest mountain. They have recently found that the upper mantle contains between 2 and 3% water. That's enough water to fill all of our oceans three times over. That's a more than enough water, but when that much water comes up the tectonic plates come together pushing out the current ocean waters to be part of the flood waters. So you add the two and you have more than enough water to flood to the highest mountain. https://www.bnl.gov/newsroom/news.php?a=111648 https://phys.org/news/2007-02-d-big-body-earth-mantle.html https://www.newscientist.com/article/dn25723-massive-ocean-discovered-towards-earths-core/ Video on this: https://www.youtube.com/watch?v=kQHuyu7KQe4
