I see this mistake made everyday in my life, and it can be upsetting as such. So many times I see people who do not have a belief in God, or anything of spirituality because they use science as their "belief system". This is such a disturbing mistake to see happen, and I would like to take some time to explain why this is a bad way to use science.
Before I reply any further, it would help if you clarify how you "see people who do not have a belief in God, or anything of spirituality, because they use science as their "belief system".
Just what kind of things do these people say or do that alerts you that they are making this mistake?
