Today, I saw a tweet with an image that claims to contain the answer of Neil Armstrong to a teacher that was skeptical of the moon landing (see below).
Of course it's not the image of a real letter, that's not the point. It's about the content.
What made me suspicious is the phrase "Or you could get on the net and find …". There's no date, the letter could be from a time when the Internet did exist but the whole "feeling" of the letter makes me think it was written a few years after Apollo 11, at the latest. So either the phrase is a saying I as a non-native speaker am not aware of, or it does refer to the Internet which would make this even more suspicious to me.
I tried finding the letter online elsewhere but only ended up finding the same tweet again.
So, did Neil Armstrong write such a letter to a teacher?
