Can Ibn Abbas be mistaken in his statement that the Earth was created first, even though this contradicts contemporary scientific facts and your previous fatwas?

Scholars have differed on which was created first: the heavens or the earth. The reason for this difference lies in the implications of the Quranic verses. The preponderant view among meticulous scholars is that the heavens were created before the earth, and the verses that imply the opposite are subject to interpretation. As for the narration from Ibn Abbas which indicates that the earth was created first, its chain of transmission is weak.
