Carbon is the foundation of human beings, and the smallest unit cell in the human body uses carbon as the skeleton to build the whole human body. Carbon is a huge element in human body, and all kinds of organic substances in human body are based on carbon. Protein sugar is arranged in combination with carbon as the basic element, while silicon is only a small element in the body. Not all substances in the human body contain silicon, and even if it does, it is a small amount and cannot constitute the human body structure.

Carbon is the basic element of living things, and the constituent unit cells of living things take carbon as the skeleton, and cells constitute living things. Therefore, carbon plays a decisive role in life. The carbon cycle of human beings and various animals and plants is also based on carbon. From carbon dioxide to organic matter, from organic matter to carbon dioxide, it is based on carbon element. It is precisely because of this cycle that life in nature can be guaranteed to be endless.

Therefore, carbon is not only the foundation of human existence, but also an important guarantee for life in nature. Silicon is an element of the human body, and it is also an important element of the crust and continent that constitute the surface structure of the earth.
