The 'god of the gaps' theory is one interesting idea that I became aware of later in life. For anyone that hasnt heard of it, it basically states that belief in god begins where our own personal understanding ends. Put another way, the existence of god is needed to explain things that science hasnt currently explained to someones personal level of satisfaction.
To me its interesting because one person might be overwhelmingly convinced by scientific evidence and another may totally reject the exact same evidence. This can be a result of their own education, family beliefs, personal or religious beliefs.
The idea that we reject something we personally dont understand is extremely vain when you think about it and all of us have probably been guilty of it. The fact that an idea has not been proven is not proof that the idea is false.
Church attendance is apparently in decline. Is that a sign that freely available information on the internet has filed in a lot of gaps for formerly religious people?
