Ham would reply that Nye's "demonstrable facts" are the myths, or, rather, demonstrable but entirely misinterpreted based on the "unsubstantiated theory" that the God-given laws of nature worked the same way more than 4000 years ago,

blah blah blah

Sorry, but Ham isn't allowed to dictate the terms of what constitutes science, the scientific process, or the interpretation of results, because he refuses to participate. Ham couldn't put a man or woman on the moon, couldn't parse DNA, couldn't discover new forms of life, because his mind is closed to the scientific process. His participation in that "debate" was (apparently) a courtesy only.

And for the equal and opposite reason, Nye won't be dictating religion and beliefs to Ham or others.
