1. The implication of my interpretation would allow both spontaneous or gradual generation with God as the author of both. Whereas, your point of view limits God to simply observing a phenomenon and exclaiming "hmm, that's weird."
2. Again, this is a concept you either pretend to not understand or actually do not comprehend. If our image, personality, disposition, outlook, tendencies, were known by God before we were "created" then random chance is not a factor in our lives. Design becomes the only mitigating factor in our existence. For example, we process the world through our senses, sight for example. Did God know we would see? If you say yes, then you have to assume we were designed with eyes.
So, God knew what a lamb was before life existed. Again, random chance cannot exist. The law of contradiction applies. If there was an idea of what a lamb is before the world began, then the evolution of a lamb cannot be by random occurrence.
3. The idea of image of God includes everything. God is a Spirit so He has no body, however, after the incarnation God has a body and reproductive organs. So then, if God transcends time and the fullness of the Godhead dwells bodily in Jesus Christ then we are made in the image of Christ (God)
