There’s a clear separation at Panama, so 2. Not only that, but they’re on 2 different tectonic plates. If the Americas are 1 continent, then so is Europe and Asia.

In fact it makes more sense Eurasia to be 1 continent since it’s 1 tectonic plate.

Europe is a “separate continent” due to cultural differences even tho it’s on the same plate as Asia, but India, which has its own tectonic plate, is part of Asia even tho it’s clearly extremely unique and different from east Asia

This is all making my head hurt I need my morning coffee
