Where did the universe come from? Atheistic origin science has no answer.

nuclear energy caused the explosion; by the way, a nuclear bomb can detonate without 'dropping'.

So, like, remember what I said earlier, about christians thinking that if they respond to one thing on a list, the entire list disappears?

And nuclear energy isn't the cause of the explosion, the trigger is: without the bomb being triggered, you get no explosion. According to your own definition of what causes are, that makes that the cause. Just one little button push.
