When asked if you believe in the existence of god the answer is either yes of no.
Any doubt in the existence of god would make you an atheist...it matters not whether you have any knowledge of god.
If all material effects/movements are caused by something physical, then why assume a meta-physical being set in motion the ultimate first cause?
Lets not forget uncaused events like the vacuum fluctuations that occur all the time.
It would seem that our universes' existence does not require a cause

The universe in all it's complexity created by an even more complex being that doesn't require creation...sounds like pure lunacy to me.
I love Occam's Razor...the theists ought to check it out.
