Why are there giant concrete tunnels in the desert?

Man is made of dust and water. If you mix the two you get mud, the most useless substance in the universe. And yet God through Christ created Adam in His image from this material. Genesis 2:7. Wow. 
You can try and explain the complexities of gravity and call it science  till you are blue in the face. In other words you are still a billion light years from understanding a fraction of it. 
Let me explain gravity that a child should be able to understand.
God is the Creator and Author of gravity. When Jesus ascended to heaven, it took him less than 24 hours to get to his destination, the throne of God His heavenly Father. He didnt need a spacecraft or a space suit or oxygen to survive the trip or anti gravity matter to assist Him in His travel through space a billion times faster than the speed of light. He simply revealed by His ascension that all matter whether animate or inanimate and the laws of the universe are subject to Him because He created everything. God created the universe through His Son Jesus Christ and appointed Him "heir" of everything that was created. Hebrews 1:1,2
 Didn't Jesus say that if you have faith as a mustard seed, you can move mountains? Didn't the storm obey His voice?Didnt He defy gravity by walking on water? Wasn't time named after Him (BC or AD)? Didn't he cure every disease? The greatest physician in history? Didnt He perform the first surgery by putting Adam to sleep and took out Adam's rib and created Eve from this? Didn't  He raise the dead to life? We call these phenomenal works a "miracle" and yet science refutes it and tries to duplicate it. It is an impossible task. Do you want to live forever in His Kingdom in heaven?
Then read John 3:16,17 for the secret to eternal life before it is too late.😇🥰
