That is the point though...what is the "literal reading" according to how the Jews understood the word "
yôm". (day)
We ourselves use the word to mean more than a literal 24 hour day....so did they.
If we speak of our grandfather's "day", we understand exactly what it means. Or we might speak of 'the dawn of a new era'. meaning the beginning of a new time period or age.
Its knowing how the original language is understood that is important...not how it sounds in English.
Bible languages also have different phrasing to ours. God is not limited or restricted by the rotation of our tiny planet.
See how long some other planets take for a single rotation....
Mercury 58.6 Earth days
Venus 243 Earth days
Earth 23 hours, 56 minutes
Mars 24 hours, 37 minutes
Jupiter 9 hours, 55 minutes
Saturn 10 hours, 33 minutes
Uranus 17 hours, 14 minutes
Neptune 15 hours, 57 minutes
Pluto 6.4 Earth days
This makes the time period for creation to be in literal days rather meaningless.
Venus e.g. takes 243 of our days to rotate once.
Mercury takes more than 58 days to equal one of ours.
Time doesn't mean much to an infinite Being who is outside of our planet's time.
