Here's why:

* Abundance: Red dwarfs are the most common type of star in the Milky Way. They are small, cool, and faint, but there are simply a lot of them.

* Lifespan: Red dwarfs have incredibly long lifespans, lasting trillions of years. This means they have had plenty of time to form.

* Size and Mass: While they are small compared to our Sun, they are the most common type of star.

While stars like our Sun are more prominent to us because they are brighter, red dwarfs are the vast majority in the Milky Way.
