A good way to learn why Satan has dominion over the earth would be to examine the few words he is reported to have spoken:
In Genesis chapter 3, he accused God of being a liar and not having the best interests of humans at heart. He also insinuated that man would be better off setting their own standards for right and wrong.
In Job 2:4, he included all mankind in his statement that
"Skin for skin. A man will give everything that he has for his life."
At Matthew 4:9, he offered Jesus control of the entire world in exchange for one act of worship toward him. Jesus did not deny Satan's control; rather he directed attention toward his father.
Satan was not able to turn Job; and he failed to make his case against Jesus. Yet, many still believe man is better off setting their own standards for right and wrong. My dear friend Frank is one of them. You may read his assertions in this thread. I am of the opinion that God has long had more than sufficient evidence to end Satan's rule and relieve mankind. But I am not in control of God's timepiece. Given the large scale extermination of ungodly humans foretold in the book of Revelation, perhaps we can take some comfort in God's patience.
