In only a few generations, our species will either successfully 'grow up' to become 'Future Man' - or become extinct. To survive we have to shed our tribal past and become united as a species, committed to a noble future that could span millions, or even billions of years. But how can we do this? In search of an answer, the author draws upon current scientific knowledge to review the events that bring us to this crossroad, beginning with the 'Big Bang' and then tracking through time to the beginning of life on Earth and the emergence of Homo Sapiens as an intelligent species - before considering man's spirituality and its manifestation in the many competing religions today. Our religions, in their extreme 'fundamentalist' form, have evolved into monstrosities that are doing far more harm than good. Are the atheists such as Richard Dawkins ('The God Delusion') right in rejecting the idea of God as 'superstitious nonsense'? The future looks bleak - but there is a way!
