You are 14 and think God and satan are the same? Satan was a FALLEN ANGEL or did you skip that part in the Bible? He HAD pride that is what led him to be kicked out of heaven with half the angels whom we call demons.
People suffer because of the sin and because Adam and Eve made a choice to disobey God. Disobedience brings disaster every time.
God does NOT want robots he wants people who want to worship him NOT people who are forced to.
I'm only 14 but I have no doubt about it. They ARE the same entity. There is SO much contradiction in the bible but if God and Satan were the same being THAT WOULD EXPLAIN EVERYTHING. "Why does God let people suffer if he's so 'all powerful'?" An athiest would say. Now, I believe in God totally, God IS all powerful but if God is Satan then so is Satan but God also promised to "free us from Satan." Meaning, he wants to destroy his 'other side' once and for all. Also, there has been SO MUCH CONTROVERSY in the story of Job. "If God is 'all powerful' why did he submit and let Satan do this and how did Satan get to heaven to begin with?" some say. Because God is all powerful and no one can trump God except God. So the other side of God tries to take over. He's all powerful. His biggest asset is his biggest curse.:(
Though he promises to get rid of it.
