The amount of water from each source (rain & subsurface water) needed to flood the world

[Neo_Frisk]

That 'fact' immediately set my mind to question the basic assumption that the center of the earth, the core, is a molten hot mass. Science has long taught us that the core of the earth is a hot molten mass. It is believed that this is where the lava from volcanoes comes from. So naturally, my curiosity was piqued by your claim that there isn't any proof that the interior of the earth is particularly hot.

What say you?

Man has never dug very deep into the Earth. Basically, the holes reach a point where the Earth is too hard to dig anymore. This quick search on Google quotes "After 24 years of digging, and several branches in the hole, the deepest branch of the Kola Superdeep Borehole stopped in 1994 at 12,262 meters (about 7.5 miles). It's only nine inches in diameter at the bottom. It is still the deepest hole in the world, and the process of drilling was incredibly difficult."

That 12.262km is the deepest hole might not be precise, but it's in the ballpark. If the Earth is roughly a 12,742km ball, that's less than 0.1% of its depth we've ever dug into. I understand it's true that temperature does increase with depth, but there is no real proof that the Earth has molten magma at it's core. We haven't ever reached close.

From the bible, it may be implied that Hell is underground. If this is physically true, it's certainly true that it would be hotter deeper under the Earth. But again, the bible doesn't mention molten magma in Hell.
