Why it is important to include a credit for any content we use from internet??

Copyright is the legal concept that works—art, writing, images, music, and more—belong to the people who create them. According to copyright law, any original content you create and record in a lasting form is your own intellectual property. This means other people can't legally copy your work and pretend it's their own. They can't make money from the things you create either.

You can still cite and refer to other sources (including copyrighted materials) in your work. But to use, copy, or change a copyrighted work, you need permission from the person who holds the copyright. This permission is called a license.

That's all I know
