Have a consistent understanding of the Bible

In your opinion, it is impossible to seriously understand what is said in the Bible.
But you do criticize those who try to give rational explanations for the miracles of Egypt. For example, the tides in the Red Sea or a solar eclipse in a plague of darkness.
No explanation is acceptable to you, and all fantastic stories must be understood literally.
On the other hand, when the Bible tells of over a million Hebrews leaving Egypt, you claim that it is not necessary to accept this, even though one and a half million Hebrews leaving Egypt is not that fantastic (even though it is less acceptable from other approaches).
 
So what's the point – can we understand what the Bible says or not?
 
And even when you try to build a certain line for your understanding, how can you build something on it with the two examples given above, when in my opinion it is the less rational explanations that are accepted by you (Hans), and where perhaps it is possible to grasp a hint of rationality (the number of those leaving), so in your opinion is it okay to compromise?
