It's best to be polite

There are a few actions you could take on this but it might not save your job. Employers and everyone else simply need to understand that when they get you to lying about things you really are lying. Even recently I saw an article that claims the earth shows evidence of a large massive flood in the past. WTF? Is it the Grand Canyon? Maybe it has hidden drains somewhere. Science is our best model. There is little evidence for having it your way unless it's at Burger King.

Perhaps a polite response such as "We can agree to disagree" is in order. No one has the right to insist you agree with their nonsense belief nor to goad you into an argument with them.

If an argument is attempted at the spur of the moment or in a social setting, I would think it rude to create a scene by engaging in one with such emotional charge. If challenged, I would probably offer only the most basic objections to their nonsense and then say something like, "this isn't the time or place for such a debate," and would try to change the subject. "You know, I heard the funniest joke the other day ...."

If the situation is with an employer, the only time such a conversation might be allowable is if you work for a religious institution. Any other employer could be in trouble with a hefty lawsuit, although with the current wave of religious freedom nonsense gaining strength, we might have more difficulty asserting this right for freedom from an employer's religion in the coming days.

Please just ask for evidence or ask a question that is disguised as if you are not asking for evidence. Example? Yes please . Fight fire with fire, Fight resistance to science with science.

This question is more nuanced that it may appear, at least to me subsequent to reading an excellent book by Israeli historian Yuval Noah Harari.

Your example is a good one to illustrate a folly most of us laugh off, and would not affirm absent a threat of violence. Easy peazy.

But what about other commonly held beliefs that are patently false, the kind Professor Harari discusses in his book Sapiens? There are many, many of these: the US is "real" when it, like any other country, is just an invention of humans and could go away; it is not natural for two males to have sex together; pieces of paper with printing on them and numbers on the corner, i.e. money, have value, etc. There are too many examples to list. Most of the false beliefs, non-scientific, are not religious, but they are true for those who believe them. I can spend American $$ anywhere in the world. People are willing to die for their "country", which has only existed in a nano-second of history.

So yes, the religious are easy to single out as non-scientific. We are too, folks like us on this site are just less so.

Interestingly this subject came up in regard to vaccines - with the proponents stating that is gets better results if you allow the person to reach thier own conclusions. Bringing to the forefront the MISINFORMATION that leads the person to believe the way they do. I understand this gives empathy , that anyone can be misinformed . We all revisit facts learned in the past and see if they correlate to TODAY'S info and reality. I am surrounded by VERY religious people & institutions ( which carries to politics too ) so I see the benefit of this approach , otherwise the situation breaks down and nothing changes - in fact most people DOUBLE DOWN and refuse to look open mindedly at the subject AT ALL. They will also refuse to communicate/ interact , and isolate from others with different views or insights about certain subjects. This can be emotionally charged if you have a DEEP relationship with the person & the subject matters to you ; and can resemble a landmine field.
People I am not connected to , I don't invest much energy in the outcome- I plainly avoid the conflict involved...it just isn't worth trying and could escalate swiftly.

Yes, marriage...

It depends on what their problem is with the truth. I dislike lying intensely, so doing so to continue someone else's delusion seems pretty ugly. I'm not above lying, but this doesn't sound like a good reason.

People should be able to believe whatever it is they so desire, so long as they aren't doing anything criminal, and I reserve the right to ignore them. As soon as someone attempts to preach to me, I walk away from them and they usually get the drift fast. They could insist however much they like, I still wouldn't care. As for employers insisting on such, I wouldn't work there, and they would probably be reported for discrimination. As for the last question, have yet to be in that position, not that I can recall anyway, and usually keep my personal views to myself.

No. Do not enable them.

I have never had an employer who was even remotely interested in what I believed in, except for my first full time + employer, the US Army. Then I had to swear to uphold and defend the constitution, and I was really OK with that and I would do it again today, in fact I've never stopped doing it. If it is an acquaintance who is asking what I believe in, that will depend on the social situation. In a work based setting I'm not going to advertise I'm an atheist, no sense in giving anyone at work any ammunition for anything. My work life and social life are pretty strictly separated. I've never had to have that conversation with any of my neighbors, and I've lived where I am for almost 8 years. The siblings I associate with are well aware of my beliefs. If any acquaintance starts spouting flat earth or other untrue BS, I'm likely to just walk away. I have given up on being the idiot whisperer. If I judge the beliefs a danger to me I may speak up, or may just remove myself from any contact with the. Some of the best life advice is "choose your battles." If it is endangering one of my offspring I will come out swinging, if not, they're a failure of the education system and I don't have time or strength to take that fight on.

I think, "praise be" is a standard answer that would get you off the hook ! Lol

Fortunately that has not occurred to me in this beacon of freedom (/s). I have had political candidates impressed upon me and didn't go along so employment was fairly short.

You are best off not trying to get scientific with uneducated Christians. You are better off expecting they will believe anything from the bible. Tell the Christian they need to watch the left behind series and that they need to realize they have been left behind. It may scare the piss out of them when they realize the biblical bottomless pit is what we now call the universe and that they have accepted the mark of the beast-666 which is identification for taxation and government control. The biblical text points out what happens to those that have accept the mark of the beast and if they do understand that it could scare them shitless and shut christianity down world wide causing all kinds of worldly chaos on a biblical proportion when Christians find out Jesus character is Angelic lord of host Lucifer the devil.

I haven't met anyone who has laid their goofy beliefs on me, so I'm not sure what I would do other than leave when l have an opening. I might tell them I'm a non-believer. You can't fix stupid, so l am not going to try to get them to see it differently.

You can say that you respect their belief but that you don’t share it. And offer them a chance to hear what you have to say.

Q: What if you were talking with an acquaintance and they started telling you that the Earth is 6000 years old? Would you politely tell them that their belief is wrong - possibly bringing up evidence such as fossils and DNA?
A: Yes

Q: What if they insisted that you affirm that their belief in a young Earth was true?
A: They would go away frustrated

Q: What would you do if they were your employer? What if they made such affirmation a requirement of you being employed there?
A: If it was a government employer, I would get the ACLU to file 1st Amendment law suit on my behalf. If it was a private employer, I might quit, but maybe not. If they harassed me at work I would file a hostile workplace lawsuit.

Q: Have you ever felt that you had to affirm something you didn't believe in yourself? What was it? What did you do?
A: Not that I recall

Anyone that starts talking to me about religion, flat earth, covid hoax, 5g causes covid etc. . . Anything that is against logic, common sense or science they are instantly ignored

Let's get at the WHOLE truth here.

First of all, I really don't have time to be an atheist or anti-theist; to me that would be Iike arguing with a 3-year-old about how Superman flies. A slow learning 3-year-old! To me the propagation of religious bull shit is evil. Small children should not be told the lie that something ever came back from the dead.

But there are humanitarian people from many religions who do honest, hard work. I have worked with them. They do not write on the food. "This food was brought to you by god". The food was grown by farmers and brought by truck or ship. Anyone that can't get out of their comfort zone needs to do a little rethinking.

I just say, "you're kidding, right?" And then look at them like they're CRAZY.

So long as their belief system doesn’t affect me. Their system may bring comfort to them. If they wish to debate me me so be it.

Here is a rock. This natural rock proves supernatural cannot occur. This natural rock is more powerful than supernatural.

Your science of nature can do nothing to disprove anything purported as being supernatural.

You must learn better logic to try and "disprove " to someone that has personal experience of supernatural. Just because a person has their evidence of supernatural does not mean they can give you their evidence. It would only be testimony of their supernatural and not a direct evidence for you. You cannot logically oppose someone else's direct experience.
