As these possible structures are proven to work, the creationists strawman gets more laughable by the minute.
The typcial creationist argument is:
1. Assert that there is an unbridgeable gap between A and Z.
2. Scientists discover N.
3. Assert that there are two unbridgeable gaps, one between A and N and the other between N and Z.
4. Lather, rinse, repeat.
Eventually, it will be reduce down to an argument that there is an unbridgeable gab between A and A. At that time, they will be forced to switch tactics.
