I find it interesting that there are those that would believe Adam was ignorant of anything. Was he not a created being of God? If Nephilim had advanced knowledge, would it not stand to reason that Adam did as well?
I agree with you. Adam was likely far superior to us in intellectual capability. His mind was neither contaminated by a sin nature nor the “dumbing down” effects of false teaching, and he enjoyed a face to face relationship with God, learning all he knew directly from his Creator.
We get our perception of Adam through the false notion that early man was barely superior to the apes and monkeys from which they are claimed to have evolved. But the Bible says no such thing, portraying Adam and Eve as direct creations of God who reflected His image and walked and talked with him. It would be hard to imagine two more opposite perceptions of our first ancestors.
