How are we physically connected to the Earth?

I'm so sorry if it sounds like a silly question.

Neil deGrasse Tyson once beautifully said, "We are all connected: to each other, biologically; to the Earth, chemically; to the rest of the Universe, atomically."

So, our physical connection with the Earth is chemical, because the elements in our bodies can all be found in the Earth, right? Or is there more to it?

Thank you. :)

For me, I would think Energy too would listed in your equation somewhere.
