God knows EVERYTHING
So when you find something that seems impossible and don't know the answer or even how to find out the answer, then
Because God knows who knows
And if you ask nicely he might just put you onto the person who knows the answer to your question
PS Often a person is good to ask, but it can be hard to find the right person without God's help. Don't ask God directly for the answer to your question, that would be simple and we know that God is not simple. Just ask him "who knows?"
