I'm afraid
this is totally wrong.
I used to be a National Geographic subscriber. Not really a "fake news" publication, on the contrary, a reference for scientific independence and accuracy. I already posted this video that can explain very clearly to 6-yrs-olds (and who have not been brainwashed by religion or politics, older people can still be saved from cretinism !) how things work. It dates back to years ago, which makes it all the more relevant.
To be checked, but I think this video is 15 years old :
