Well, yes. We are built from the Earth - our atoms cycle with the Earth’s over and over again.
The Moon was created after a collision with Earth, so some of our atoms are from the Moon, too.
Then ultimately, the Earth and the Moon were made of leftover material from the sun’s formation.
But the heavy elements that we rely on for life weren’t made in our sun - they only form in much more massive stars, ones that must have existed long before our sun was formed.
So actually, yes! We come from planets, the Moon, and stars themselves.
Our Sun is a second- or third-generation star.
All of the rocky and metallic material we stand on, the iron in our blood, the calcium in our teeth, the carbon in our genes were produced billions of years ago in the interior of a red giant star.
We are made of star-stuff. - Carl Sagan
