I agree: There is no flat Earth. Remember the sitcom "As the World [Earth] turns ? I prefer the rolling hills. ;o)
Dayspring does not mean morning star.
what specific Scripture compels you to adhere to such a belief that the sun and the stars all revolve around the 'circle of the earth' (Isaiah 40:22) in one 24 hour period? Do you dispute the passage in Job 38:12-15 that CLEARLY states the earth spins like a potter's wheel ("turned as clay") and that it is the morning (sunrise) and dayspring (morning star) 'stand as a garment' with fixed stations (yet also have apparent circuits as per Psalm 19).
Job 38:12-15 Have you commanded the morning since your days; [and] caused the dayspring [side of earth facing the sun or morning] to know his place; That it might take hold of the ends of the earth, that the wicked might be shaken out of it?
It [earth] is turned [revolved] as clay [to] the seal; and they stand as a garment. And from the wicked [dark side facing night] their light is withheld, and the high arm shall be broken.
Hermanuetically [I beg to differ ;-)] there is no other way to interpret this passage: Two objects, the morning sun and the dayspring (morning star) are locally fixed and are the 'they' standing as a garment. The 'they' which stands as a garment are the morning and dayspring, and from the wicked THEIR light is witholden. The IT is the EARTH and IT (the earth) is TURNED AS CLAY (like a signet seal on a potter's wheel).
The Earth faces the Sun in the morning: That is the dayspring or morning side of the Earth. At night the Earth faces the dark side or nighttime. Stars and Planets have an heliacal rising with the Sun. The Star Sirius is used to determine the length of the year and was used by the ancient Egyptians when it arose with the Sun as the New Year when the waters of the Nile flooded: It is now used by us when it crosses the meridian at midnight at the winter solstice in Greenwich, England.
1 Thes. 5:5 “Ye are all the children of light, and the children of the day: we are not of the night, nor of darkness.”
How would you interpret this passage in Job differently?
The heavens and the earth were 'created' out of nothing. On the third [fourth] day, the sun, moon and stars were made or appointed (H6213) for the purposes of determining signs, seasons, years, days, etc. In other words, our solar system core [hub] sun [earth], planetary motions, Mazzaroth, moon, stars, were APPOINTED or fixed for the purpose of determining TIME. The greater light (sun) and lesser light (moon) already existed previous, but was appointed or MADE [created] on the third [fourth] day for the benchmark purposes of time.
If the planets are not included in the purview of 'stars' as being made for the purposes of time in Genesis 1, when did God make them? On the 4th Day Genesis 1:14-19 “And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years:  And let them be for lights in the firmament of the heaven to give light upon the earth: and it was so.  And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: he made the stars also.  And God set them in the firmament of the heaven to give light upon the earth,  And to rule over the day and over the night, and to divide the light from the darkness: and God saw that it was good.  And the evening and the morning were the fourth day.
[The stars/constellations were there but the Sun, Moon and Planets were the POINTERS TO THE CONSTELLATIONS TO TELL HIS STORY IN THE HEAVENS.]Psalm 19:1-4 “The heavens declare the glory of God; and the firmament shows his handywork. Day unto day utters speech, and night unto night shows knowledge. There is no speech nor language, where their voice is not heard. Their line is gone out through all the earth, and their words to the end of the world. In them has he set a tabernacle [habitation/place/path/ecliptic] for the sun,”
