How have rivers affected life in europe?

Europe is not a typically dry place (unlike for exampe Mesopotamia) so it does not need rivers for irrigation.

Instead, rivers are needed more for transport - they have served as a means of communication and for the exchange of goods.

For example, Danube allowed a big-scale trade between the cities lying on it: Vienna, Budapest and Bratislava.
