"Religions all require you to believe in things that cannot be proven, despite their being unlikely"
Sounds like quantum physics... which also has a large number of people (spending money) that believe in something that can not be seen or proven. Physicists around the world a dedicating a large amount of their lives to theories many of which ARE MUTALLY EXCLUSIVE meaning someone is going to be wrong. Mathematically 'proof' exists of a 4th dimension... but just because the maths 'adds up' and it could be possible doesn't mean that it does exist, yet many many smart people believe that it does. Before you bust on religion I suggest you educate yourself some more belief in things that do not exists is not limited to relion but also a healthy chunk of the scientific domain. The irony is that Steven Weinberg IS JEWISH and a physicist that believed in the Higgs boson at one point... to date no one has seen any traces of the Higgs boson.
