Good points.
On your point 1, note that under Fred Franz's chronology, the entire universe was only 49,000 years old, not 13 billion. So that objection wouldn't have been an issue years ago.
Ol' Fred's thinking was nutso bonkers, but at least it had internal consistency.
The current crop of numnuts don't have a brain between the lot of them, so they didn't realize that they destroyed that internal consistency when they (a) changed the "creative days" from "creation of the universe" to "preparing the earth for human life" and (b) changed them from exactly 7000 years long each to "many thousands or millions of years".
