Sadi, so long as all gods remain undetected in any way, even through their supernatural intervention in the chain of cause and effect, their existence or nonexistence is equally unfalsifiable. That means nobody has good warrant to believe in one or more deity. The time to invest belief in something is after it had been demonstrated to warrant belief.

The burden of proof always goes to the person making a claim. It's not up to skeptics to prove no gods exist, it's up to theists to demonstrate that what they believe is justified. All I said is that the arguments I have heard from theist are all flawed with fallacies and thus fail to persuade me that anything supernatural exists.
