I did not ask theists these question because a theist would admit that the world cannot be understood completely by human beings.
From a theological perspective you are heading in a very, very bad direction.
It is called "god of the gaps". You find things that we don't currently know (and may or may not every know) and suggest that they are some support for your beliefs. Just because physics doesn't know everything doesn't mean you know a single darned thing about the universe.
In fact, using god as an explanation of unknown things has been an historically really bad idea. Over and over the gaps in knowledge close. No, the sun god does not charge across the sky in a chariot; no, god does not throw lightening bolts (though some current so-called Christians actually think he throws Hurricanes
) and no, demons do not cause disease.
In addition, no god flooded the earth in recent times etc.
The reasons for people's beliefs are NOT on topic in this thread. Nor does it belong in the science threads. Stay on topic.
