No problem the Genesis account of Creation is 100% fiction, and was understood as described by Christians as a flat or rounded disc domed heavens fixed in space at the center of the universe.
The Roman philosopher Lucretius was the first to propose a modern cosmology. It was the Greeks that began to conclude that the earth was a sphere until the Greek view began to dominate after the 5th century.
It is not only the Genesis account, but many references throughout the OT that support a flat or domed earth supported by pillars fixed at the center of the universe.
The view of a fixed geocentric earth remained the dominate view until. the15th and 16th century. The Bible provided no guidance for more modern cosmology. The authors or compilers of the Pentateuch, OT, and gospels and the Church Fathers believed in a literal Pentateuch and Torah. For most of the early believers in Christianity these views were by far dominant, because they believed in a literal scripture.
Some of the Biblical references:
Daniel 4:10-11: “These are the visions I saw while lying in bed: I looked, and there before me stood a tree in the middle of the land. Its height was enormous. The tree grew large and strong and its top touched the sky; it was visible to the ends of the earth.”

Some today actually still argue for a planar earth as a fixed geocentric universe based on the Bible:
Plane Geodesy
The on light for heliocentric view at the times of Jesus Christ was the Roman philosopher Lucretius who described the universe from a modern perspective.
