Heliocentric and Geocentric
There were several theories about the earth which were Heliocentric and the Geocentric models. The theory that came out first and was used for years was the Geocentric theory. The Geocentric theory is a theory that says the solar system revolves around the earth. The Heliocentric theory is the theory that the solar system revolves around the sun. The theory that came out of the scientific revolution was the Heliocentric theory. The correct theory is the Heliocentric theory because it was proved to be true later on.
Galileo's Trial
Galileo Galilei was put on trial by the church for saying that Copernicus's theory that the solar system revolves around the earth is wrong and going against the bible. Galileo believed in the Heliocentric theory while the church believed in the Geocentric theory. Galileo said his opinions in public and therefore was put on trial for going against the teachings of the church. Galileo eventually lost the trial and was put on house arrest and eventually died. Then three century's later the Church said that the earth is not in the center of the universe.

The Scientific Revolution: The Scientific Method
The Scientific Method
The Scientific Method is a way to get an unbiased answer. This then turns into a theory after many tests and observations are done. The tests also must have the same results at the end for anyone who wants to conduct the same experiment for it to be true. The scientific method goes in this order observations, hypothesis, predictions, tests, and then a theory is made. If the other scientists agree to the theory it is believed to be true.
Experiment That Uses The Scientific Method
A Experiment that uses the scientific method was Galileo's experiment from the leaning tower of pisa. This experiment was to prove if you drop something from the same height with one being heavier and one is lighter and to figure out which one will fall first. Galileo did this experiment on the leaning tower of pisa and dropped various objects of different weight. He then saw that no matter what the weight is it will drop at the same speed. This was then tested by other people and got the same results therfore Galileo's theory is correct.

Evolution Vs. Creation
Evolution
Darwin's theory of evolution is that we evolved from what is know as a common ancestor. We evolved slowly, piece by piece and eventually formed all the different animals today. Darwin's theory explains how we evolved from a common ancestor through natural selection. Natural selection helped organisms to have an advantage in the habitat they live in, for example if a organism lived in a area with tall plants it will adapt and eventually get the traits needed to reach them such as long arms, long neck, height, etc. The organism then survives to pass down traits to offspring.
The organisms without the traits eventually die out and it allows the ones with the necessary trait to survive. This theory also explains that this happened gradually over time. The organisms keep the good traits and gain more traits to eventually form a new organism. The organism also removes unnecessary traits.
Creation
Creation is a religious belief that God had created the world and life which includes the first humans on earth. Creation is based on the Bible in the book of Genesis. This theory is believed by the Christian church and explain that the first humans on earth Adam and Eve and eventually led up to the humans now. Creation also rejects the fact of natural explanations such as the theory of evolution.
I believe in the theory of evolution because it is based on science. This means that there is evidence to back up the theory. Creationism does not have any evidence except for the Bible and it is based on belief. Evolution on the other hand has proof that organisms adapt and change over time which is know as natural selection. Creation in my opinion doesn't show how it created the humans today.
