That's a great question! It's true that we usually think of seeing stars at night, but the answer is actually a bit more complicated.

Here's the breakdown:

* Stars are always there. Stars are giant balls of burning gas that emit their own light. They exist 24/7, day and night.

* The Sun's light blocks out the stars. During the day, the Sun's light is so overwhelming that it drowns out the light from the much fainter stars.

* We can see some stars in the daytime. Under very specific conditions, such as high altitudes, clear skies, and being away from city lights, you might be able to spot a few very bright stars like Sirius during the day.

So, while we primarily see stars at night, they're always there, even during the day, but hidden by the Sun's brightness.
