: How do you know that there are other galaxies if we can't even see out of our own? I know that scientists see light but how do you know that the light isn't coming from somewhere in our galaxy?

Astronomers have extremely powerful telescopes such as the immense 10m Keck Telescope that can see galaxies. Even backyward astronomers with a sufficient aperture lens have been able to take astrophotography of some magnificent galaxies.
