? How is this evidence for that god doesnt need a cause?
It's not meant as such. I was trying to make the point that 13.7 billion year old universes don't cause their own coming into existence but are contingent on a cause that can 'decide' when and whether a universe should exist.
To use the analogy of a light switch turning a light bulb on or off, then 13.7 billion years ago the light was switched on. Did it turn itself on?
If so, why 13.7 billion years ago and not earlier?
Perhaps the switch unexpectedly (spontaneously) turned itself on for no reason at all. But then arent we left wondering whether the universe might 'magically' disappear spontaneously?
This is possible but how is the light bulb mysteriously turning itself on and off more tenable than a causal agent/mechanism scenario in which Someone intends the light to be switched on? Why is God (and the afterlife) such an objectionable scenario?
