No, there's something more there.
Is Satan even mentioned in Genisis? How could God say on the 6th day that he looked at the earth and saw it was good if evil existed and was lurking?
Yes, our souls are an image of God. They are not God. God is perfect. We are not perfect. An image of something is not the original, nor is it identical to the original. For example, we are three dimensional creatures, but our mirror image is only two dimensional. Our mirror image does not have a soul. It is not exactly like we are.
There was no evil until Adam and Eve ate the fruit.
I did not say this, nor imply it. Clearly, Lucifer existed before Adam and Eve were created given that he tempted them. When Lucifer, a fallen angel, was created by God he, as all angels, was infused with perfect knowledge of natural things. He was also given free will to choose God or to reject God. At this point, he didn't see God. Only angels who choose God are able to see Him. Angels who reject God are cast into hell. Lucifer thought he could be God - he was very prideful. He rebelled against God and was cast out of heaven.
We are like God, but not God. Just as a mirror image is like us, but not us. He has given us all that we need to be with Him for the rest of eternity - to know, love and serve Him - if we accept His plan for us and do not reject Him. Those who go to hell have made that choice. God merely ratifies their choice. He does not make the choice for them. He wants all of us to choose Him and spend the rest of eternity loving Him.
Yes, the devil tempts us (because he does not want us to go to heaven), but we always have God's help to resist those temptations if we just ask Him.
