For that matter, why did they call themselves “he brews” if they weren’t making beer?
Besides the accurate responses you received about separation of the Hebrews from surrounding cultists, the Jewish sages over the centuries summed up the reason for the mandate as:”It is bad enough to kill a baby animal to eat, but it is far worse to also then boil it in it’s mother’s milk.”
Essentially, the rational has evolved into a moral stance.
