Can you use a quote as a thesis statement

No you can't.

Explanation:

A thesis is your own thought on the subject. Using someone else's thoughts/quote would not be a proper thesis statement.

Using Direct Quotations in Your Thesis or Dissertation. Whenever you quote the exact words of another author or speaker in your thesis or dissertation, it is essential that you quote those words with accuracy and observe with precision and consistency all appropriate scholarly techniques and editorial styles.
