What causes day and night?<|im_end|>
<|im_start|>assistant
Day and night are caused by the Earth rotating on its axis. When the part of the Earth where you are is facing the Sun, it's daytime. When it's facing away from the Sun, it's nighttime.<|im_end|>

Why do we see stars at night and not during the day?<|im_end|>
<|im_start|>assistant
We see stars at night because the sky is darker, making them more visible. During the day, the bright sunlight makes it harder to see the stars.<|im_end|>
