Phrase describing a debate with a misinformed person

Can anyone think of a word/phrase/idiom/expression or anything else I am missing that describes when someone is attempting to lecture, convince, or try to change your mind on something that you know far more about than they do. Often I find it comes from well intentioned that just do not know any better. Sometimes it can be quite frustrating and I am trying to find a phrase that I can use to convey this in my own thoughts, or to others.

For some context I have 20 years of experience in the Oil industry as a Petroleum Engineer. Lots of times people will try and lecture me about things that they think they know about, or just read about in some news article but are hugely misinformed on. I find lots of articles on the internet on some technology related website that is trying to stir the pot on something that has been around for 20 years, people read them show them to me, and try and push about them to me.

The most recent example I can think of was my neighbor trying to tell me about using nuclear steam generation in heavy oil sands development to replace other methods of production. Which without getting technical is not a new idea and is not a very good idea for lots of reasons. I tell them this, and they argue/debate whatever you want to call it about why I am wrong.

Another common example is when people say something like 'artificial intelligence will leave all oil workers out of a job, plants will be fully automated' and so on. I usually say this idea has been around for over 50 years and is sold by a company trying to hype a product that is not very good. To which they double down and try harder to convince me.

Thank you in advance!

Perhaps this old saying describes the situation.

There's a difference between mansplaining, mentioned in one of the comments, and the above saying.

• Mansplaining is, at its core, a very specific thing. It's what occurs when a man talks condescendingly to someone (especially a woman) about something he has incomplete knowledge of, with the mistaken assumption that he knows more about it than the person he's talking to does.

• Wikipedia describes mansplaining (a blend word of man and the informal form splaining of the gerund explaining) as a pejorative term meaning "(of a man) to comment on or explain something to a woman in a condescending, overconfident, and often inaccurate or oversimplified manner".
