The young earth creationist interpretation is internally inconsistent; it just doesn’t make sense. Both earth and life exist before the sun, moon, and stars. This leaves a person to wonder where heat, light, gravity, and earth’s rotation and orbital features came from prior to the fourth creation day. Let’s look at the sixth day. How in the world did Adam do so much? Here’s a list of the events of day six:
- God creates the various living creatures along with wild animals and animals that become domesticated [nephesh/soulish creatures] (Genesis 1:24-25).
- God creates Adam in the divine image (Genesis 1:26-27; 2:7).
- God gives Adam a mandate of dominion over creation (Genesis 1:28).
- God makes the plants available as a food source for man (Genesis 1:29-30).
- God plants a garden and puts the man in it (Genesis 2:8).
- God gives Adam instruction concerning obedience to God’s specific commands (Genesis 2:9, 16-17).
- God commissions Adam to cultivate the garden (Genesis 2:15).
- God commissions Adam to name or classify the animals (Genesis 2:19-20).
- God declares Adam’s need for a suitable helper (Gen. 2:18, 20).
- God induces sleep and performs surgery on Adam (Genesis 2:21).
- God creates Eve (Genesis 2:22).
- God ordains that Adam and Eve enter into a divinely constituted marriage relationship (Genesis 2:23-25).
Now when it comes to naming the animals, that’s an incredible task! Let’s do a little math here. By young earth leaders’ estimates, there would have been about 30,000 pairs of land animals at the time of Noah’s flood. However, the fossil record documents at least half a billion species or more. Never mind the fossil record for now, I will just go with the YEC claims. Now there are 86,400 seconds in a day, that means just to name the animals Adam would have had just under 3 seconds to name every land animal (never mind birds and ocean animals). Now, with just three seconds to name every land animal Adam still has to be created, be put to sleep, and have Eve created. I find this highly improbable for this hyperactivity to take place on Adam’s behalf (and this is just day six, I haven’t even gotten into the problems with interpreting the other days as 24 hour periods of time. Even if you want to claim a lesser number of land animals at the time of Noah, you’ll still need to account for micro-evolutionary timeframes of speciation (which is an evolutionary speed that even Darwinists don’t claim) and that new X number of seconds to name all the animals.
Thus, just given all the events in day six makes the days of Genesis highly improbably to be literal six twenty-four hour days.
