As researchers your job is to find, evaluate, interpret, and make meaning from the various sources you encounter during your research. This means you are supposed to build your arguments and ideas from the work of previous researchers - so when you're engaging with that research, it is important that you acknowledge the individual(s) who originated that idea or information. Similarly, if you base an argument over a specific piece of research that later turns out to be incorrect, your integrity as a researcher will be less jeopardized if people can identify that you were working with information that was thought reliable at the time but was later disproved or changed.
As previously discussed, part of a book or article being credible is being able to track where information and ideas came from. If someone on the street told you 90% of Americans have red hair, you would rightly question where that data was coming from. People reading your research have those same questions, so let them know that you're not pulling figures or other information out of thin air - you got that information from a reliable source.
Finding, evaluating, reading, analyzing, and incorporating sources into your research is HARD WORK. Show off all the effort you put into your project by citing all the sources you used and referenced.
One excellent way to find additional information on a topic is to look at the sources used by an author in their work. If those works aren't cited - finding those other sources becomes harder. Similarly, sometimes you read about something that's only a minor part of the larger work you're reading. If you want to learn more about that particular topic, seeing what sources the author referenced for that section will help you get started.
