Or are you implying that God didn't exist prior to the Bibles codification by the Council of Nicaea in 325 AD??
If the very fist line of the Bible is accurate, your “eternal universe” is not.
“In the beginning God created the Heavens and the Earth”
Whoever your God of an eternal universe is - it isn’t the God described in the Bible. That is fine, many people worship many different gods - not of the Bible.
The evidence points to a universe with a finite beginning.
You can argue evidence or you can argue God, but arguing that God manipulated the evidence is just preposterous.
