In terms of human, the Bible says right off the bat, first thing first: God created man and woman.
27 So God created mankind in his own image, in the image of God he created them; male and female he created them.
Why the need to be so word for word (when it's clearly only 2 genders?), unless maybe he's preparing us for today's world?
Is He perhaps trying to tell or warn us that anything other than man or woman is not God's creation. Preparing us for today's crazy world.
How did the serpent fool Eve? Not by an outright lie, young padawan, but by mixing a lie with the truth.
Truth: ye shall be as God, knowing both good and evil.
Lie: ye shall not surely die.
That is how nominal Christianity has fooled billions and its not just in the doctrine.
God saw that creation was good because it was exactly as He intended it to be. Nothing goes down that isn't already ordained from above, including the fall.
God, ultimately, is responsible for EVERYTHING.
