I know that there are many cases of cultures having whacky ideas of how exactly babies are made, however in most of these cases they still link the creation of babies to having sex (however weird the link may be). My question is the following:
Is there any strong evidence of historical (or current) cultures, in which the link between sex and the creation of babies was not understood in the slightest?
If not, I would accept an answer that comes the closest. Thank you.
(I apologize if this is the wrong stack exchange, I tried looking for what I deemed the most fitting)
