Revelation, parables etc. are not literally true. This is a feature not a bug and in no way invalidates Jesus’ life. What Genesis is exactly is a hermeneutical question. We don’t have to freak out about it.

I should clarify myself. I believe all of the passages that don't have strong reason to be taken allegorically, are literal. Passages like Genesis 1-11 are written in a very literal way, but most people today take them as allegorical. When AI is trained on literal and allegorical passages where there is no disagreement and then asked if Genesis 1-11 is literal, it says literal. Jesus and the disciples refer back to Genesis 1-11, creation, Adam & Eve, and the global flood and consider them literal. There is zero textual reason to take them allegorically.
Revelation is harder. There are images, like the harlot on a red beast, that are clearly meant to be taken allegorically. I, however, think that much of the prophecies described in Revelation will be fulfilled literally. As technologies are created that make these predictions possible, I become more an more convinced of this reality.
Can someone still conclude the bible is the literal Word of God even if they believe the whole thing is allegory? Once that is concluded, the logical next question for them to ask would be, "Why would God lie?"
