If we took material like rock from space and got it back to Earth enough times, would Earth grow as a planet? (sh.itjust.works)

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?

~~> energy equals mass~~

~~That doesn't mean energy has a weight.~~

~~It means it is physically possible to transition energy to mass and vice versa. Sunlight hitting the earth does not add any weight.~~

Edit: turns out that part was wrong

Also, earth radiates heat out to space. At a rate of (aaaaaaaaalmost, because of the greenhouse effect) 100% of the energy we get from the sun. If it didn't, earth would be a few million degrees hot by now...
