How do you feel about religion? Furthermore, the whole concept that a theist has to be able to provide some sort of "proof" that other people can see is absurd.
I've never seen Alaska. Alaska exists whether I've seen it or not.
The non-theists don't know why the theists believe. You don't know what the person has experienced to make them believe. I've read Bertrand Russell, Dawkins, Sagan, etc. I've studied the atheist side and I know it pretty well.
Dawkins is pretty shallow philosophically. Same for Sagan.
Russell is above them but I still think his arguments are weak. If anyone wants to discuss arguments, let them discuss them.
We are not disembodied minds. We are people and we have experiences. Allah guides whom He wills.
Epistemology from an Islamic perspective is totally different from most Western epistemology and Western-minded people will likely attack it because the epistemologies are alien to each other. My thinking won't necessarily fit into someone else's preconceived framework (frequently based on the presuppositions of the Enlightenment).
I wrote a blog post discussing this further
