To own the copyright for your creative work, you need to create the work and fix it in a tangible form. This means expressing your idea in a physical or digital format, such as writing it down, recording it, or creating a digital file. Once your work is fixed, you automatically hold the copyright. However, to protect your rights, it is recommended to register your work with the U.S. Copyright Office. This will provide you with legal evidence of ownership and the ability to take legal action against infringement.

To file a copyright for your creative work, you need to submit an application to the U.S. Copyright Office. This application typically includes information about the work, such as the title and author, and a copy of the work itself. Once the application is processed and approved, you will receive a certificate of registration, which provides legal protection for your work.
Under US copyright law an independent author or artist must intentionally contract in writing to lose ownership of the copyright of his or her own creative works. A copyright in your own work of authorship is a personal right and should not be "automatically" transferred to (or "stolen" by) others.

Copyright protection begins as soon as a creative work is fixed in a tangible form, such as writing it down or recording it. This means that the work is protected without the need for registration or any other formalities.
Copyright protects the rights of the creator of a work.
In order to use copyright-protected materials that are not your own original work, you need permission from the rightsholder; this is usually in the form of a license, which can be as broad as a Creative Commons license or (more often) specific to your proposed use.
