It is considered whether UFO reports rather than indicating something real provide a symptom of the current religious cultural situation in Europe. Should rational life elsewhere in the universe be real, it is argued that biological life would be a neccessary condition. The divergence and convergence hypotheses are examined. The fundamental prerequisite is the existence of other solar systems with planets other than our own. Insights from biology and astronomy are placed in the context of philosophical discourse.15 pagesPDFAfrikaansFaculty of Theology, University of PretoriaExtra-terrestrial intelligenceDivergence hypothesisConvergence hypothesisConvergence (Meteorology)Divergence (Meteorology)Outer spaceArticle
