How can we be sure the days of creation were six literal 24-hour days? Take a look at these six biblical reasons.
1. Evening and Morning Qualify the Length of a Day
On day one of creation, Moses (the
author of Genesis) uses the terms
evening and morning to qualify the
length of a day since they refer to
the end and beginning of a day.
The length is defined in Genesis 1:5
by a numerical quantifier, one day
(yôm ’ehad). Why is this important?
Moses is defining day, the turning
of the earth one time on its axis to
distinguish between the light and
the darkness (a period of 24 hours).
2. God Told Us that He Created the Earth in Six Days
On Mount Sinai, God clearly
told Moses, “For in six days the
LORD made heaven and earth,
the sea, and all that is in them”
3. The Sun Wasn’t Needed for the First Three Days of Creation to be Literal Days
Some believe that the first three
days cannot be ordinary days
because the sun was not made
until day four. However, this
argument presupposes that the
sun is necessary to have a day
marked by evening and morning.
But to have an evening and
morning on the first three days,
all that was needed was a rotating
earth and a light source, which God
created on day one (Genesis 1:3).
4. The Bible Indicates that the Seventh Day of the Creation Week Was Also a Literal Day
Those who think that day seven is
not a 24-hour day because it lacks
the refrain “evening and morning”
misunderstand the use of this
phrase throughout the creation
week. In the first six days, each
day is shaped by a structure:
- “God said . . .”
- “Let there be . . .”
- “There was . . .”
- “God saw that it was good.”
- “There was evening and
morning . . .”
Because the seventh day is not a
day of activity, but a day of rest,
it is not necessary to use the
“evening and morning” formula
used in day one through day six.
The fact that the seventh day is
numbered like the other days is
further evidence of a 24-hour day
5. God’s Command Immediately Brought Creation into Existence
When God spoke the divine
command, “Let there be light”
(Genesis 1:3), it was immediate.
It did not take millions of years
for the universe to come into
existence (2 Corinthians 4:6).
6. A Literal Six-Day Creation Aligns with God’s Purpose for Creating Earth
God created earth to be
inhabited by mankind (Isaiah
45:12, 18). Why would God wait
billions of years for man to
evolve if his intention was to
have human life on the earth?
Six literal days of creation makes
sense considering what Scripture
