No, it isn’t the world’s oldest profession
Regular reminder: prostitution is only the “world’s oldest profession” if you have a misogynistic and transactional view of sex (i.e. women only ‘give’ sex in exchange for favours from men). Otherwise it’s a relatively recent (~5000 years) urban phenomenon that is pre-dated by agriculture, trade, and even carpentry by another 5000 years..
That is all.
