Because the Bible is totally lacking in accuracy and detail regarding the Creation.
You comment does not explain the arrogance of “scientist” using the word impossible in regards to data the contradicts their own theories.
I could understand such a statement for a natural law but cosmology is hardly a natural law subject!
As as for creation and the Bible, yes it is not detailed (I disagree with your accuracy accusation, it is indeed accurate), the Bible is our Lord’s word to help man live and grow close to Him, to know his will. It is not an instruction manual on how He creates. It gives hints and the Bible has been used to discover the nature of our physical realm scientifically.
Look up Maury Fontaine, his faith in the word of the bible lead him to discover ocean currents we know and use today!
