Some folk are very intelligent but at the same time very dumb as they question and even deny the Bible. Why would I say that? Well, ‘The Mississippi River dumps an average of about six million gallons of water into the Gulf of Mexico every second.  Where does all that water go?  The vast surface of the ocean allows for enormous amounts of evaporation to take place.  High in the atmosphere, this invisible water vapor condenses into clouds, which produce rain or snow, which in turn falls onto land surfaces.  The water then completes the circuit by flowing into rivers and then back into the ocean again.  

No one really understood or accepted the idea of the complete water cycle until the late 16th and early 17th centuries.  Pierre Perrault, Edme Mariotte, and astronomer Edmund Halley all contributed valuable data to the concept of the water cycle.  Yet Solomon and Isaiah both wrote about it in the Bible.

In Ecclesiastes 1:7 King Soloman describes the water cycle as follows,

 Ecclesiastes 1:7 All the rivers run into the sea; yet the sea is not full; unto the place from whence the rivers come, thither they return again.

This hydrologic cycle was quite accurately described in the Bible thousands of years before it was understood scientifically.’http://www.searchforthetruth.net/

Dr. Henry Morris said in his Defender’s Study Bible ‘1:7 thither they return. Similarly, this is an excellent summary of the earth’s amazing hydrologic cycle, as confirmed scientifically only in modern times.’https://www.icr.org/books/defenders/3752
