It's also quite possible Jehovah chose not to know... And since the only evidence we have is Gen 3:15, I tend to think he didn't. The scenario you present has Jehovah creating Satan even though he knew what he was going to do. If I was going to create life, I wouldn't want to know how it was going to turn out, I would want to experience events as they unfolded. What's the purpose of creating life, if you already know the outcome? We can speculate all day long, and someone could even say your going outside what the Bible says, but since I'm not that kind of guy, I simply say we know what we know, and that is the first time anyone foresaw the future was Gen 3:15, and that is what we know. We've discussed this in great detail already in the other thread though.
