I will also make enmity between you and the woman, and between your seed and the seed of the woman. A woman's seed will hurt your head, and you will hurt his heel. The "woman's Hou Yi" here is Christ! Everyone is a man's Hou Yi, and only Jesus was born of a virgin and became a flesh! Therefore, it is a woman's Hou Yi, so that it will not inherit the original sin of human beings and will not be polluted by sin, which is a qualified sacrifice to replace human beings!
God clothed Adam and his wife with skins. After the ancestors committed crimes, God made clothes for them with animal skins, which means that life died for them. This is redemption.
And the ark built by Noah, which is also a prophecy of Christ! Just enter the ark and you will be saved!
