Atheism is irrational.

[Edwardo Piet]

...thereby dismissing an entire branch of human inquiry. I suggest you call your local University and advise them to shut down their Philosophy Department. See how they feel about that suggestion.  

Here's how the thread has played out thus far:

"Here is my straw man refutation of the 5W."
"Well, even if my refutation doesn't apply someone sometime did so I don't need to."
"Well even if I cannot produce a valid refutation it doesn't matter. All propositions require empirical verification (except this one.)"
"Philosophy is bullshit."

Pointing out a limitation of philosophy is not the same thing as calling it bullshit. Can you give an example of something besides God that philosophy can prove to exist without evidence?

God isn't an exception to the unprovability of the existence of entities via a priori logic.
