If this is a homework question, you'd better search your book thoroughly for the answer, because they probably want a specific wording.
However, the basic reason is because he knew they weren't. He made an unprecedented number of planetary observations, and it was clear to him that none of the charts adequately explained their apparent motions. Kepler would later use Brahe's observations to deduce his laws of planetary motion.
Brahe himself seems to have favored yet another incorrect model, in which the Sun and the Moon orbited the Earth and the other planets orbited the Sun. (Mathematically this is equivalent to the heliocentric model, but had some advantages if you were Catholic in the 16th century and didn't want to get excommunicated, particularly if you were very careful to explain that it was simply a mathematical convenience and of course everything orbited the Earth as God had clearly ordained.)
Aristotle believed in a geocentric model of the universe, with Earth at the center and celestial bodies orbiting around it in concentric spheres. He also theorized that the universe was eternal and unchanging.
Christopher Columbus's goal was to find a new, western route to Asia for trade and exploration. He believed that by doing so, he could acquire wealth and spread Christianity. This promise of increased trade and potential riches convinced King Ferdinand and Queen Isabella to fund his journey.
In Christian and Jewish teachings, God is believed to have created the firmament, separating the waters above from the waters below on the second day, not the ninth day. On the ninth day, God rested from His work of creation, according to the Bible in Genesis.
Kepler discovered that the planets orbit the Sun in elliptical shapes, not in perfect circles as previously believed. This finding is summarized in Kepler's first law of planetary motion.
Aristotle believed that the universe was geocentric, with Earth at the center and celestial bodies moving in perfect circular orbits around it. He also thought that the universe was eternal and unchanging, consisting of a series of concentric spheres made of a quintessential fifth element, ether.
A supernova. He was able to measure that this event took place very much farther away than a our solar system.
The ancients believed that the firmament was a dome which held up the waters above, separating them from the waters below. Later in the first creation story, the sun, moon and stars are simply small lights placed in this firmament.
The firmament is as imaginary as the Garden of Eden. Consider the evidence: Genesis 1:7 says that the firmament divided the waters above from the waters below. Genesis 1:14-17 says that God set the sun, moon and stars in this firmament, just above the earth. We know that neither of these descriptions is true - there is no water above, because the rain originates in evaporation from the ocean; the sun, moon and stars are far distant from the earth. If we did believe that the sun was set in the firmament, as the ancients believed, then of course the firmament would not filter its light.
The philosophies of Parmenides (being is unchanging) and Heraclitus (being is ceaselessly changing) seem to be irreconcilably opposed.
Before the Big Bang theory, many scientists believed that the universe was static, or infinitely unchanging.
The Greek philosopher Parmenides famously argued that motion is an illusion of the senses and that reality is unchanging and indivisible. He believed that our perceptions of motion and change are deceptive and that true knowledge comes from understanding the unchanging nature of the universe.
Parmenides believed that change was an illusion and that reality is unchanging and eternal. He argued that true knowledge could only come from understanding the unchanging nature of reality, rather than the ever-changing world of appearances.
One example would be Abagail Williams. Before the witch trials had happened she was just a normal teen in the small town. After it all went down she pretty much had the power of arresting and hangings. All she had to do was accuse someone and the elder believed them. Except for a few but she had the others so convinced no one believed the others and they were punished.
He himself claimed to have received the word of Qur'an. His previous life was a proof of his honesty and truthfulness. By and by people were convinced and they believed in him.
The unchanging spiritual essence known as Aatma or Soul does not die ever. It is the body, the container of that soul, that dies again and over again like change of a dress. That is why it is called as rebirth or reincarnation as believed in Hinduism
On the second day God created the firmament, an imaginary dome which was believed to separate the waters of the heavens from the lower waters. Apart from this, there is no mention of anything created on that day. If we no longer believe that the firmament is a physical reality, then no work was done on the second day.For more information, please visit: http://christianity.answers.com/theology/the-story-of-creation
he says he is and it is a believed fact, but im not entirely convinced. You probably already knew that, but yeah
