On my post concerning the Creation Museum, an anonymous commenter said:
"Notice atheism really has no evidence at all."This person said it as if I was trying to hide the fact that atheism has no evidence. That couldn't be farther than the truth. In reality, the absence of evidence is the strongest case atheists can make against the existence of a god. Allow me to explain.
I consider myself a scientific atheist. Therefore, I feel science is the best tool we have for understanding the workings of the universe. Now, science is driven by evidence. Evidence is necessary to support or falsify any hypothesis or theory. Without evidence, no conclusions can be drawn either way. It simply is not considered.
Additionally, something that does not exist will, by definition, be incapable of leaving any evidence. This fact should be self-evident, but many seem unable to grasp this concept.
Anyway, this lack of evidence for a god has two implications. First, science can only work with evidence, and, since there is no evidence of a god, science must remain grounded in naturalistic explanations of the world. It cannot consider supernatural events for which there is no evidence. However, if evidence of a god did arise, then it would no longer be supernatural and would fall into the realm of the the natural world. At that point, science could then consider it. Nevertheless, that evidence has yet to appear.
Second, as a scientific atheist, I base my worldview on evidence and the conventions of science. No, I cannot prove that God does not exist. However, a lack of evidence is as close as science can come to proving the nonexistence of something, as I explained above.
In conclusion, atheism does not have any evidence. But that is the strongest scientific case atheists can make against the existence of a god. The burden of proof remains with the theists because they need to produce the testable, verifiable evidence that would establish God's existence. Until then, I see no reason to spend my time worrying about something that is not powerful enough to leave even the tiniest shred of evidence.
