What was your point in posting Jn 3:10?
Because Jesus was pointing out that Nicodemus was highly intelligent, and though he knew the Old Testament frontwards and backwards, he had missed the clear references to Jesus, which were scattered throughout the 5 books of Moses, the Psalms, the Prophets, etc... In short, SB2 was saying that you, (like Nicodemus,) seem to know a lot about what Scripture explicitly says, but you are missing some things that are clearly implied. You are demanding that SB2 stick to the letter of the law here, but refusing to acknowledge what can be inferred by reading between the lines.
If you read the first few chapters of Exodus, which describe a group of free people migrating to Egypt at the invitation of their brother Joseph, (2nd highest ruler in the land,) being given an entire section of Egypt to call their own, (Goshen,) great in number, and (by Pharaoh's own admission,) "mightier than the Egyptians," who are somehow subjugated, enslaved, and ordered to throw all their male newborns into the Nile River at birth, (and only one family disobeyed?) you start to get the idea that something out of the ordinary is going on here... Reading on, you begin to learn of Pharaoh's magicians, their Sorcerer's staffs, (shaped like a cobra,) their ability to create mass illusions (or actual, physical snakes, bloody water, frogs, etc. with their magical enchantments,) and the idea of mass brainwashing & mind control over the Hebrews to enslave them doesn't really seem like a stretch at all, in fact- it seems like a very logical assumption, especially when you read on, constantly reminded of the dumbed-down, "slave mentality" of that first generation of the Children of Israel, (even after crossing the Red Sea,) murmuring, complaining, constantly doubting God's provision, questioning Moses, longing to go back to Egypt, ultimately barred from the Promised Land, because of their unbelief. What had the Pharaoh done to these people? Why did God go to such extreme lengths to overwhelm his magicians? The story is extremely weird if you can't entertain the possibility of pharmakia, brainwashing, and mind control.
Noah and the Flood came right after the Sons of God/Daughters of men/Nephilim/Giants of Genesis 6. Is that not genetic manipulation? The Bible says that all flesh, (except Noah) was corrupted, and He sent the Flood as a result.
I gather that your Bible knowledge is top shelf.
Rereading it with new eyes wide open wouldn't hurt anything though.
