Are the churches using atheists to gain more converts?

In Europe even religious people seem to be familiar enough with science and history, not to have to rely on literal interpretations of religious teachings for their cosmology, biology and such.

And you would be wrong in overestimating the European education systems. Religiosity in Europe is weaker in general, but you can still see the same gap as in the USA. Between the large hubs and the rural areas.
