Is there a biblical reason to limit information about creation to Genesis?

Here's a debate between Hugh Ross of "Reasons to Believe" and Ken Ham. These men are popular spokesmen for each of Old Earth and Young Earth Creationism, respectively. In the hour-long discussion, Ken repeatedly shuts down any use of passages other than Genesis to get information about the details of creation. For example, he didn't want to talk about how Job (9:8) or Psalms (104:2) speak of God "stretching the heavens" Setting aside the whole YEC/OEC debate for the moment, is there a biblical reason to limit creation-detail information to the book of Genesis?
