"each day of creation was a literal 24-hour day"

This is overwhelmingly the case in Genesis 1.

Each of these days has a morning and an evening.
Each of these days is numbered.
Exodus refers to these days as literal 24 hour days.
The Sun and the moon were made to govern these days.

When day is used as a period of time, such as "in my father's day" it never has a morning or evening. It is never numbered and the context and sentence structure is entirely different than what is used in Genesis.

The days in Genesis are 24 hour days.

Each of these days has a morning and an evening.

The sun wasn't created until Day 4, if my memory serves me correctly. How could there be a morning and an evening without a sun?
