What factor was likely responsible for the location of europe's first civilization? it is a landlocked area. it is between three continents. it has a temperate climate. it was not threatened by seismic activity.

The first of Europe's civilisations was on Crete and it was organized by the Minoans. It's an island, so it can't be landlocked.
