believing in something you see or touch or hear is not a faith, it's realization.
for example, people in the past have a "faith" that there are things that cause illness, but it wasn't realization until the invention of microscope that allowed us to see bacteria and viruses.
"is allah (god ) created himself?" wrong question, creation concept itself is created by Allah to fit our minds. you simply don't realize allah, you believe in allah, and sure you can support your believe by many evidences and proofs to make it logic to your brain circuits.
another work around to help here, since begin and end, life and death are all creations of allah, you simply can't apply these laws on the creator itself. it's not logic, right?
ofcourse non-belivers will read these and laugh, but it's a matter of faith not realization, one of the most repeated concepts in quran where it's get emphesised tenth of times is insightness of the human being.
