"God doesn't Exist"- Claim or Conclusion

[Tonus]

Because there are multiple and conflicting truth claims does not mean that one of them is true to the exclusion of the others. You say there is no way to determine which claims are correct--perhaps, but we can examine the overall theological framework of each religion and see which one is internally consistent, which one best matches claims against reality, which one makes more sense of more observations, and which one has the best predictive value when examining issues of xyz.

Yeah, but if one of them was the God's honest truth, wouldn't we expect an overwhelming number of people to follow it? The assumption is that only one religion would fulfill the criteria you described. After centuries of study and experience, not only do we still have many different major religions but each of them is fragmented into thousands of denominations with varied interpretations of almost every major tenet of their faith.

[1] Did you mean that is is reasonable to employ the scientific method to the truth claims of religions because of the reasons listed or do you mean that in general, only through the scientific method can we learn anything?

The latter. It's the one method we know that helps us to find answers while dealing as best it can with limitations in existing knowledge and understanding, as well as with the countless biases that can corrupt our attempts to learn more.
