So saying "abandon our rational mind" is just a rhetorical mechanism to establish that perhaps this is the wrong question, and we should reframe what we understand as absolute or relative.
You're incorrectly interpreting my words as a call for irrationality. I'm just saying that our interpretation of the universe and the debates about its origins are often based on ideas that can't be challenged because they are scientific truisms.
The problem is that anything that doesn't comply with our standard interpretation of the universe will be deemed esoteric and unscientific. Therefore, it neuters debates that could yield a valid interpretation of the universe.
