The First Cause

God can be called the First Cause.
But does the First Cause still have its "own" cause?
I am asking such a logical question, because everything, even the universe, should have its cause.
The scientific universe is described as space-time, where everything is interconnected, creating a chain of causality.
However, in a state beyond time and space, where time does not pass and there are no points of attachment, such a chain of causality does not work.
Because God exists beyond time and space, He is not subject to the principle of causality functioning only in space-time. There is therefore no "His own" reason. In summary, God is a perfect and absolute God with no beginning or end, and therefore cannot have any "His" cause.
He, Himself is the absolute First Cause.
