Yes.
The scientific method is the best way to decipher reality. It is derived from reasoning by answering the question how can we know what is in reality and how can we explain it.
If you can come up with a method that is better than a scientific method me and probably the rest of the world would be happy to hear it.
This is an older post in the thread, but I think it's worth bringing up here. One of the issues I have with the notion of "proving" god has to do with how we define "reality" in the first place. The "reality" as acknowledged by the scientific method is a fairly limited rendering of that concept. It is in part because of this that science has limits as a discipline. It is not very good at dealing with Idea as a component of reality, only the impacts of Idea on human behavior.
By Idea, I basically mean anything which can be said to exist in the "mind" but resists reductive quantification by the scientific method. This would include abstract concepts like "love" or "aesthetics" and "justice" but also concepts like "deity." Attempting to scientifically prove these concepts doesn't tend to work very well. They clearly exist in some fashion of the meaning of existence, but science as a method is poor at framing them for understanding (or when it does frame them, it misses some of their essence).
This is where things like personal experience come into play, and with deity specifically, an individual can readily have personal experiences that they attribute to deity. But I'll leave that thread hanging for the moment.
