Limitation of language and human understanding resolution.
Just for hypothetical argument ,
Lets say supposed to be GOD tells you to ask a question ...
You ask what is the end of the universe...
God says X is the end.
You ask again what is the end of X?
God say Y is the end of X.
You ask again what is the end of Y
God say Z is the end of Y.
..basically Human mind can only running in cricles with how much resolution words can go.
Even though GOD do not exist ...it is just to show that beginning or end of anything is beyond human limits because words has limitation. It is macro language to simplify things for brain to act in minimal set.
When humans evolve in to communicate through direct energy like other animals , he probably can see and understand his role in the universe.
At present he is making up things as goes along. Just a lie.
Today's truth will be tommorrow( future) false eventually.
Basically things are true only in defined boundary ( a single context). Same thing will be false in another context.
And humans waste all his energy try to prove why he is telling the truth when in fact he is telling the truth in infinitesimally small context.
Ask questions , never agree or disagree.
