Why do you think early astronomers believed that the sun went around the sky and that Earth was the center of the universe?

The belief of early astronomers that the Earth was the center of the universe stemmed from limited astronomical tools and geocentric attitudes. The Ptolemaic Model, developed around 100 A.D., presented the Earth-centered solar system in which most early Roman astronomers believed.

In the early 1500s, Nicolaus Copernicus published the first major theoretical work that challenged the notion of an Earth-centered universe. Copernicus theorized a sun-centered universe, or a heliocentric solar system. In 1610, Galileo Galilei was able to use the first telescope to study the solar system. He strengthened the argument for a heliocentric system by noting changing levels of brightness during the rotations of certain planets as well as the Earth's moon and the sun.

pepin the short[a] (german: pippin der kurze, french: pépin le bref, c. 714 – 24 september 768) was the king of the franks from 751 until his death. he was the first of the carolingians to become king.[b][2]

the younger son of the frankish prince charles martel and his wife rotrude, pepin's upbringing was distinguished by the ecclesiastical education he had received from the monks of st. denis. succeeding his father as the mayor of the palace in 741, pepin reigned over francia jointly with his elder brother carloman. pepin ruled in neustria, burgundy, and provence, while his brother carloman established himself in austrasia, alemannia and thuringia. the brothers were active in suppressing revolts led by the bavarians, aquitanians, saxons, and the alemanni in the early years of their reign. in 743, they ended the frankish interregnum by choosing childeric iii, who was to be the last merovingian monarch, as figurehead king of the franks.
