Where did all the water come from?
Is the only real question I have after reading this chapter. In verse 11 and 12 we read the following:
11 In the six hundredth year of Noah’s life, on the seventeenth day of the second month—on that day all the springs of the great deep burst forth, and the floodgates of the heavens were opened. 12 And rain fell on the earth forty days and forty nights.
For a very long time creationist have been claiming that most of the water didn't come from the sky but from underneath the earth itself. That most of the flood waters where the result of geysers etc. The problem here was that there wasn't proof of a giant reservoir of water underneath the earth. In 2014 they found possible proof of that. On top of that, the earth's surface is about 71% water.
If the earths surface was completely flat, so no mountains or oceans the earth's surface would be covered by a water layer of approximately 2,4 km deep. This is without all the water that is currently contained beneath the earths crust. So there is no shortage of water to make a thing like a global flood possible.
One of the arguments some people have is but there isn't enough water to cover mount Everest (8,848 km) but they seem to be forgetting that it is not because we currently have a mountain like that on earth that it existed when the flood happened. I will go into a bit more depth in my next post where I'll discuss where all the water went after the flood etc.
There are, of course, many more theories about this. So if you feel like it you can go and dive in this very interesting topic.
