Has Modern Science killed God?

I’ve been a member of possibly the last ever generation to be brought up as Christian as a matter of course. Those responsible for my education as a boy would find that shocking; in the 1950s it was the perfectly natural way of things. Then, as I got older, I started picking up that some people thought that Science had overtaken God; that Science had made God unnecessary; that Modern Science had even killed God (as Vaclav Havel claimed). This was almost the default position of anyone who left school in the 1960s.
