On the last part of day six, God created man (a human) containing both man and woman. At that time of creation there existed no physical beings, all were spiritual and perfect. God created man and gave them complete authority over the earth; He said: “let them have complete authority”.
It is as if you are asking somebody for something, and the person says let him have it, then by the witnesses it is yours; it does not belong to that person anymore. God by what He said here transferred the authority over the entire earth from Himself and over to the man, He said “let them have complete authority”
In Psalm 115:16 this is said: “The heavens are the heavens of the LORD,
But the earth He has given to the children of men.” God has given the earth to men for them to cultivate and administrate it; the intention was peace and growth and satisfied people. But men were created with free will and could do what they pleased.
God said; “Be fruitful, multiply, and fill the earth” The earth is big and rich enough, we can multiply and fill the earth, it is food enough for everyone being born on the planet earth that God made, it is plenty. But today there is much for few, but little or nothing for many. The earth is suffering from war and starvation. The earth is ruled with hate, selfishness, and lack of knowledge.
