Saename, much appreciate what you said which makes sense and all, but religious belief and the scientific module are two ways we as humans make sense of the world around us. In that way they are similar because they can lead humans to their path whether right or wrong. Here's why they are just as similar. Someone who believes in God and feels that there is evidence in creation believes that it is "evidence" based on how they see it.
Someone who has pride and commitment to scientific faith bases their commitment on what they themselves see as validation. The underlying thought here is that people can see evidence differently from the next person because of their unique mind. Regardless of whether it is right or wrong is subjective because it's clear that people do in fact have a distinct outlook on things no matter what they are. What I'm trying to say is that there really is no universally veracity to this. You may believe there is and I may believe that it isn't but both of our beliefs are reflective of our inner perspective.
You remarked that the scientific method requires rejection of claims that don't involve refutable proof. The thing is that a Christian's use of creation as proof can still be proof even though it's not consolable using the scientific method as it's created by man. A believer trusts their decision to believe in God just like the person who is destined with the scientific method. However, the believer just doesn't use the scientific method to come to his conclusion. It's just a simple alternative way. Not really correct or true as this is subjective. That's how I come to the conclusion that they are similar. I never said they were totally similar but they do have complementary based on what I mentioned before.
What I said about "the true essence of who we are as human beings" is just my opinion and you don't have to agree obviously. But I will tell you why I believe this. This goes with what I told Viviane. What truly makes us different from animals? It's our brain and how it exceptionally uses abstract techniques and a special cause to fix issues and communicate. Without this, we'd be either at the same level of animals mentally or inferior.
And no. Faith is not only needed for claims. They can be needed for personal assurance in people among other things, not only just claims.
