Too much wrong to deal with everything so let's see if we can chat on one issue at a time.
"Adam and Eve were perfect and sinless before they ate of the fruit."
Perfect is as perfect does so if perfect, God would not have to command them to do or not do anything. Right?
If God is perfect and knows good and evil, then A & E would, if perfect as you say they were, then they too would have already known good and evil before eating of that tree. Right?
