Causation outside time=> infinite regress
I went on the Q&A of W.Lane Craig's website. On the topic about "causality, time and God", WLC claims that causality can operate in atemporal state, but this raises the problem of the "before Universe" which doesn't exist outside time,
but WLC states that causality can be conceived differently: effects can be "simulatneous" with their cause (no delay between them both) this means that if a cause is eternal its effect would too. This seems consistent in atemporal state.
Thus God (atemporal) caused Universe at the same time it "begins", to Craig.
On the other hand, God is described as causeless by WLC for He is outside time and has no beginning.
But isn't this a contradiction?
if we follow Craig's concept of atemporal "simultaneous causation", then the cause of Universe can depend on another cause; since the latter is timelessly present, the former as well.
Then, in this case, we'd have a possible infinite regress of cause even outside time?
