Personally, if something's unexplained I don't feel compelled to come up with just any explanation. As to proving God doesn't exist, I can't prove the little man who turns my refrigerator light off doesn't exist either. Does this mean he must really be in there? It's not possible to prove a negative.

I must say this thread stayed on-topic as to personal experiences and people resisted shoving it into the usual 'religion' argument for longer than I expected...
