OK, so what was sauron and how did he come to middle earth? and when he was defeated on the slopes of mount doom when isildur cut the ring from his hand his body died but his spirit stayed right? so how does he get his body back? how does he take psyical form again? this has troubled me for ages. and why did he need the one ring, i reckon he might have been able to take middle earth without the whole ring idea thingy. Pls help! im confused!
