“Where did God come from? How did God emerge out of nothingness?? “
In order to even ask that question intelligently, one has to understand the qualities of “nothingness”...even science has no asnwer for that one. Scripture says that God made both the qualities of light and he had to make the darkness as well. It stands to reason he had to make fullness and emptiness as well.
If the God we worship ever had a cause, then we should have to reject that God and worship that which caused God!
To even ask those questions actually shows a LACK OF study, not “too much thinking”.
To answer them though - God has no cause, God is ever-existing (”ever” being a non-applicable concept anyway, as God made time), and made everything else out of nothing by His spoken word.
