The body works in a wonderful way just like tweaking the machine. All organ systems in the body depend on each other to survive in some way and form. Cherif et al. (2010) point out that the body relies on accurate movement of each organ to maintain human physical, mental and emotional health. Also, body balance, temperature regulation helps to maintain the function of the body. The skin system (skin) is the largest and most important part of the body.
The human body is a very good example of God's engineering; a system of symbiotic elements that can not be complicated. But at the most basic level, our body is made up of Stardust, just like everything else in this incredibly enormous universe. Simplicity leads to complexity. This is the fractal nature of things. Every natural system relies on maintaining the right balance of its optimal function. Take the pH value of our body as an example. The closer our pH is to 35-7.45, the more likely it is to be healthy and fight against the onset of disease. If this deviates even a little, the influence may become catastrophic.
It is a good thing to feel hungry. Our body is a fine-tuning machine that has evolved for millions of years and is suitable for single target and survival of fitts. Hunger is a general signal from our body to the brain. Taste is the signal that our body sends to the brain. Since we use it in the cell, we naturally need salt and fat. Because vitamins and minerals are important to our body function, we are looking for sweetness and sourness of fruits and vegetables. This is our natural driving force and essential to our survival of the fittest.
Evolution can explain why our body is tweaked and why the design seems to have spectacular handicrafts. It also explains why there is a tendency to see something like "design" even if there are multiple defects in the design. I explain the theory of evolution for reasons such as whether the birth canal of a human being is too small or not because there is a defect in our body or whether there is a blind spot in the human eye but not octopus. It also explains the tendency of us to overdose sugar and fat. The rest is to explain why the universe has certain constants. Several of them seem to be carefully adjusted. Natural selection can explain this briefly. If there are other universes with incompatible constants, there is no life in them. We are never aware if there is a multi-dimensional universe, or our universe is in infinite birth and death cycle (big bang followed by big bang). But this is an explanation. God is different. Simulation theory is another thing
