Why can we see the Milky Way?

Answer: We are inside it

We are inside it ✓ — Correct! The Milky Way is our galaxy—we're inside it! The band of light we see is looking edge-on through the galactic disk (100,000 light-years across). We're in a spiral arm ~26,000 light-years from the center. Dense star concentrations appear as milky band across the night sky. Best viewed from dark locations away from light pollution. Ancient cultures saw it as celestial river!

It's brightest galaxy — Wrong. We see the Milky Way brightly because we're inside it—viewing our own galaxy from within. Other galaxies appear dimmer due to distance.

Reflects sunlight to Earth — Wrong. Galaxies don't reflect sunlight—they emit light from billions of stars. We see the Milky Way because we're part of it.
