If we took material like rock from space and got it back to Earth enough times, would Earth grow as a planet?

As the title says. I’m actually thinking about this hard with my friends because everything that’s produced on Earth stays on Earth so it doesn’t change size, but what if it’s not from Earth but it stays on Earth? [https://sh.itjust.works/pictrs/image/4b10eeca-d3fc-4aca-beff-8d9cb61b303a.png]

I mean yeah. If you add stuff to a ball of stuff it get’s bigger.

Currently Earth is actually losing mass around 55.000 tones of mass per year. (100.000 tons loss due to air escaping to space but we gaing around 45.000 tons in dust and meteorties falling on earth).

If “energy equals mass”, shouldn’t we be gaining mass from the sun too 🤔

Energy equals mass times the speed of light squared. Therefore for each unit of mass you’d need the speed of light squared units of energy to create, which is a big number for our fraction of sunlight to live up to.
