The people who were seeing the visions did not know how to explain it. The science of that time said that the moon gave its own light. He saw in his vision that the Sun got dark, and AFTER that, the moon not longer was bright. According to the science of that time, the moon stopped giving its light.
Yes and the bible is wrong. the fact that they didn't understand that the moon doesn't produce light doesn't excuse the fact that the bible is wrong about it

you just contradicted yourself, you said they didn't know how to explain it, but according to their science the moon produced light, they thought it gave off light.
thus for their time they did have an explaination but it was wrong
