Translation:Who was the first man on the moon?
I mean on the recording, listen to it, the voice doesn't pitch up. So it can be mistaken to "Er war der erste Mann auf dem Mond."
oh, sorry. In German you do not have to do that much with the voice, since the words already make it clear that it is supposed to be a question. But yes, sometimes if you don't pay attention in a conversation that can happen. In this pronunciation a lot of emphasis is given to "der erste" which changes the tone of the question a little bit.
