What's the difference between back up and evidence?

D. Evidence

To support a thesis statement, you need evidence. The thesis statement is a claim or an argument that you are making in your writing, and you need to back it up with relevant and credible evidence. Evidence can come from various sources, such as research studies, expert opinions, statistical data, experiments, observations, or personal experiences. It is important to use evidence that is reliable, up-to-date, and directly related to your thesis statement. This helps strengthen your argument and makes it more persuasive and convincing to your readers.
