Kind of an absurd metric. At one point, no countries criminalized homosexuality. A nation state in general is a European concept. The earliest accepted date for the first nation state is 1648, but even then it didn't really turn into a global concept until after WW1 or even WW2. Most countries that criminalized homosexuality did so while under colonial rule
It just seems silly to start the timeline to when France, a country that criminalized homosexuality in its colonies, decriminalized it

Your confusion arises from mixing up the terms country and nation state. Nation states are modern [1]. States, what you’re calling countries, are as old as history.
States criminalised homosexuality well before there were nation states [2]. (The point at which no country criminalised homosexuality appears to be in the neighbourhood of the first centuries AD.)
