What did God create on the second day of Creation?

TL;DR:

On the second day of creation, God created the firmament and separated the waters. This way of creating and then separating calls us to trust in God’s timing and process, seeing that He has intentionality in what He does and when He does it.

what does the bible say?

On the second day of creation, God separated the waters by creating an expanse, or firmament, which we know as the atmosphere or sky, dividing the waters above from the waters below. This act prepared the earth to support life, demonstrating God's intentionality and precision. The Old Testament records this event as part of God's six-day creation process, emphasizing consistency as each day concludes with “And there was evening and there was morning, the [number] day.” Seeing the way God created the atmosphere and separated the waters highlights the importance of trusting in God's timing and process, recognizing that there is a reason why He does what He does in His way and in His timing.

from the old testament

"And God said, 'Let there be an expanse in the midst of the waters, and let it separate the waters from the waters.' And God made the expanse and separated the waters that were under the expanse from the waters that were above the expanse. And it was so. And God called the expanse Heaven. And there was evening and there was morning, the second day" (Genesis 1:6–8).
God has now begun to move the waters which were part of the creation of the earth on day one. God moves these waters twice for two distinct purposes, and here we see the first. God separated the waters by creating an "expanse" between them. Some English translations of the Bible call this a "firmament" (KJV, NKJV). The Hebrews word is רָקִיעַ (rāqîaʿ) This is considered to be something that physically supports the waters above. We call this our atmosphere, or the sky; both are representative of the same thing. This is only the first movement of the waters; the earth is still covered in water below, but now there is an atmosphere surrounding earth, ready to support the life which God will create later.

from the new testament

What God created on the second day of creation is recorded in the Old Testament.

implications for today

While the atmosphere is the only thing created on day two, we cannot overlook the consistency of God's Word in establishing that He is completing this work in six literal days. God concludes the narrative of each day's creation with the same statement: "And there was evening and there was morning, the [number] day." When God instructs the Israelites to keep the Sabbath day (Exodus 20:8–11), He tells them that the seventh day is holy because He labored six days in creation, just as they (the Israelites) labor six days at their work, and then He rested. They were to follow this example because God declared this day (seventh) as holy for them. But that is not all that is being said here; God is affirming that He created everything in six literal days. Thus, the second literal day of creation is completed with the creation of the atmosphere.

Just as God completed His work in six days with intentionality and precision, we can trust in His timing and process in our own lives. When we feel impatient or overwhelmed by the slow pace of progress, remembering the order and purposefulness of creation can remind us that God works in His perfect time. We can rest, knowing that He is actively at work, even when we cannot see the immediate results or when the results do not come in our timing and way.
