Okay kiddo, let me explain the demographic history of Palestine.
A long time ago, many different groups of people lived in the region we now call Palestine. There were Jewish, Christian, and Muslim communities, as well as many others.
In the early 1900s, many Jewish people from around the world started moving to Palestine. They wanted to create a Jewish homeland there. Over time, more and more Jewish people moved to Palestine, which caused tension between them and the other people who were already living there.
In 1947, the United Nations made a plan for dividing up the land between the Jewish and Arab communities. Many Jewish people accepted this plan, but the Arabs rejected it. This led to a conflict between the two groups called the Arab-Israeli War.
As time went on, the Jewish population in Palestine grew, while the Arab population declined. Many Arab people were displaced from their homes and forced to move elsewhere.
Today, Palestine is mostly made up of Arab people, but there is also a significant Jewish population. The conflict between these two groups is still ongoing and has a long and complicated history.
