I can't speak for OP, but in my experience it's very rare for a thesis to be just your work. It's based on data and research often paid for by the university, and includes the work of many different people. indirectly: advisors, lab partners, professors, other students. Directly: Co-authors of papers, research assistants, and other contributors. It's a messy bundle of work.
