I didn't say that they weren't caused, I asked if he could tell us what the cause was. Simply because one is prepared to accept that the universe must have some 'first' cause does not neccessitate being able to identify such a cause any more than in the cases of radiaoactive decay or the generation of virtual particles.
I wasn't trying to reiterate Ramoss's point, I was trying to see why 'but we don't know what it is' is an acceptable ascription of cause for some things but not for others.
