Which stars can see Earth as a transiting exoplanet?

Our radio waves have traveled for about 200 light years. Proxima centauri, our closest star, is located at 4246 Light years from us.

Very, very unlikely that someone can hear us, even if they tried. Space is huge.

Proxima centauri is actually ~4 light years away. Space is really big, but there are a handful of stars in relative vicinity of us (under 250 ly)

I think your Alpha Centauri distance is off by 3 orders of magnitude :)

Edit: I think there are thousands of stars within 200ly of Earth.

Here's an interactive 33ly radius model: https://gruze.org/fly_10pc/ - left click + drag, mousewheel, right click.

Could be more efficient, but this interactive does the trick; shows how loaded our neighborhood is.

Going to hamburger menu -> settings -> show labels brings it to a crawl, though filtering objects helps that a bunch.

Showing only stars with known planets is rather interesting.

This is really cool! Definitely going to be a time sink for me!
