It is a common claim among theists that god is purely faith based, untestable, and outside of the bounds of science. Maybe god even created the laws of the world as we know it. That is the question asked in the blog post “Can God be Scientifically Proven?” and that is exactly the question I hope to answer.
Theists have maintained that their god is untestable but they also make claims that this god did things which are very testable. For example, it is said that god answers prayer. It is trivial to collect quantifiable data on prayer, and people did. That New York Times article details the data which was scientifically collected which shows that prayer does not seem to have any correlation with healing.
Also relevant to the success rate of prayer is this (funny but serious) video by GIIVideo on YouTube:
As you can see, prayer is nothing but an optical illusion and is not proof for a god. Atheists, 1; Theists, 0. Although it does not disprove god, it does show what is really going on behind one aspect which theists use as proof for god.
As you can see, many theistic claims are quantifiable in this way. Also, many arguments for the existence of god have been logically disassembled on the Iron Chariots Wiki. In fact, the only claims I have not run across a way to address logically or scientifically are arguments from personal experience (which are logical fallacies so they don’t really need to be addressed) and this is exactly the proof Juan cites in the comments on the post I mentioned earlier.
Can god be tested? No. Can claims about god be tested? Certainly. They can and have been tested logically, and scientifically and no reason to believe in a god has ever been found. From the origins of the universe to prayer, there is no reason to suspect anything but natural processes (i.e. no supernatural beings).
