Could be worth a watch. I am not a huge conspiracy theorist or anything but I have to agree with your partner. My issue is 50 years ago technology was pretty basic compared to current technology and yet we have never been back since 1972, that is if they went in the first place.
Did we really have the technology to safely land on the moon, take off again and then renter the Earths atmosphere 50 years ago? do we now?
