God Made Satan, Why?

The Bible is God's Manual for Christian Living it goes from the past to the future and asks a lot of fundamental questions: Why are we hear? How are we supposed to live? what is going to happen in the end times?The book is two subjects, one is to make you understand that God has created: the weather, the honey bees and the chickens. I have studied all three and come to a conclusion that God has made everything perfectly well. The second part is Satan's attempt to frustrate God's plan, to cause man to doubt God and his work. His plan really worked, but in the end God will come and destroy him. There is going to be a judgement and God will decide which path you are on, until you die.
