The expression of an existing gene is hardly the same as creating new reproducible genes.

Millions of small changes over hundreds of millions of years certainly would equal big changes.

You don't disagree with that, do you?

The only difference between 'micro' and 'macro' evolution is the timespan.

He's debating whether or not an organism can evolve new genes as opposed to modification of existing ones.

Look, I'm no scientist but I somehow got this crazy idea that there is a much greater difference between micro and macroevolution than simply time, with macro involving changes on the SPECIES level and micro involving changes within species. Please explain to me how time of any length could change one species to another, and evidence for me when and where we know that actually happened. THAT'S what many creationists have a problem with, NOT the age of the earth. There are plenty of creationists who accept the earth being billions rather than thousands of years old.
