      Hmm I don’t think so. I’ve never heard that.

      It is true that all the elements in your body can be traced back to the stars! All the stuff we are made of was created in stars billions of years ago and found it’s way to earth. So we all did originally come from stars (but not Mars)

      We don’t really know if the original life that evolved into humans started on earth spontaneously, or was dropped on earth by a comet or some other object colliding with earth. In theory this is possible, but we have no way of proving whether we came from space bacteria, or from earth bacteria that evolved spontaneously in the primordial oceans.
