Is the US Marines a part of the US Navy?

That depends, do you mean like the Marine Corps, and not the Navy, or do you mean the Marines and the Navy?  The Navy is a department of the Department of Defense, which also oversees the Marines.  The Navy includes the Marine Corps, and the Marines operate independently within the Navy and also under the Department of the Navy.

So the Navy oversees the Marines?
user
Yes, the Navy oversees the Marine Corps.

How did that start?

Well, there are a few ways to approach that question.  One thing you can do is to say that the US Marines started with a tradition of maritime military activity, and that history started in the 18th century and eventually, eventually came to be a part of the US Navy.  It’s also possible to say that the US Marines were originally formed separately, and that they are now a part of the US Navy.  So the best answer for this question, I think, is that the US Marines started in a way that would now make them a part of the US Navy.  They were part of the Department of the Navy in 1868, and they’ve had a more formalized relationship since around the 1880s.  That’s what it boils down to.
