OMG - Flat Earthers are nuts...same ones that deny the Holocaust, Moon Landing, whatever.

Tel them to look through a telescope for the stuff left there , they won't , but then it's up to them

Why would you worry yourself with someone who obviously has no concept of reality or lacks completed education.

Introduce him to Buzz Aldrin, and let Buzz punch him out.

Seriously, if it is someone irrational just drop them, but if they are just misinformed let them know that Neil and Buzz left mirrors on the moon that are still usable to reflect light. [en.wikipedia.org]

My 1st husband was a moon denier. Every time I tried he would bring up the movie Capricorn One.

These days, you don't. Like a lot of flat earthers, they only listen to shit that they think validates what they already believe......its an exercise in futility.

You can’t get through. They are the same kind of stupid as flat earthers. Watch a few YouTube videos of flat earthers to get a feel for how futile the debate would be.

Unles they work for NASA I don’t care! I would say “OK” and leave. I doubt such a person would care if I told them that topography can cause a single light source to cast multiple shadows, or that they had no clue how hard or soft the surface would be prior to landing. I have a friend who growing had dinner with Buzz Aldrin and Robbie Kruger where Buzz decked a guy for saying it was faked, nope, just “OK” and walk away. Sorry, I don’t know why Robbie Kruger was there, I have interesting friends

Punch them like Buzz.

I just ignore them nowadays. It's a black hole stupidity of an 'event horizon' extent.

Do not discuss. Go onto another topic.

I have never met anyone this fucking stupid...

Is it important to get through to that person? If its not, move on. they belong to the flat earth crowd!

The best one I got "It was all filmed in Malta."
Said to them ever been there? You cannot fart on that little island without everyone knowing.

My wife thought Bin Ladin was an Airline, she thought the London Underground was a terrorist organisation, and she thought moon landing deniers were Astronauts that denied landing on the moon.

Im not a moon landing denier, but i've always been super curious how they managed to get through the Van Allen radiation belt. Can never find anything about it when i go looking.

If they didn't have ridiculous beliefs no one would want to talk to them.

Prove it to them.

Don’t bother. It’s one of the infinity of routes to insanity.
