Your right they can not.
But YEC ones not cause them to contradict each other.
If you think it does. You do not understand YEC
If the universe is all we can observe, taste, hear and touch, are they not valid factoids of the existence of universe. As the universe is created by God, then are they not valid factoids of Existence of God. There many nuances that can be quoted (see debate between Danny Faulkner (YEC Answers in Genesis) and Hugh Ross (OEC Reasons to Believe). See post #165.
The one that clinches it for me is the age of light, if observation of the age of the light is to be accepted and the universe is only ~6000 years old, it would imply a thing growing at the speed of light and filtering the light to look old. The image of the heavenly host being fixer uppers is too jarring to accept.
Are the universe and Scripture at odds? No as we agreed. Is the verse wrong? Definitely no. That leaves the interpretation.
YECs are correct to say י֥וֹם means 24hours. OECs say the root can be used in epoch, indefinite period of time. I think both are incorrect. YEC is too literal, and OEC too imprecise. Is God Literal? Is God Imprecise? No, God is Literary.
And there was evening and there was morning - day ....
As a day (yom with squiggle) is literally night and day, there is the redundancy in meaning in the sentence. It is used exactly 6 times and in Gen 1. This is a stipulative definition - a literary device to redefine terms. In technical reports, there is a section called nomenclature. It defines all the symbols. If you were to copy paste from a different source with a different nomenclature you would redefine only for that section. It stipulates a definition for that specific section. The day is whatever God wants it to be.
