Which of the following feels right or makes more sense to you?

north america is called a continent, and is surrounded by water like an island from north atlantic along east coast to panama canal or... further south to south tip of south america and along west coast to arctic ocean so:

is north america both a continent and also an island until panama canal?

or panama canal is too shallow to be like an isle, so land continues and the isle includes continent called south america?

which makes more sense to you?
