And more so, do you not understand that everything rests on genesis.
God Created everything.
God created mand from the ground. Physically formed him out of earth. Breathed His spirit into him. Billions of years is not the same thing.
God made woman from Adam. Not the same as billions of years.
There was no death in this world until man sinned and fell. Not the same as billions of years (of death).
God reveals that one day He will bring a kinsmen Redeemer to set things right (genesis 3) - a point ahead to Jesus Christ.
Genesis is a foundation of the faith. The concept of billions of years undermines key concepts that Genesis puts down that undergird the rest of a Christians faith. THEY know that and that’s why they attack it. If they can get people doubting it they can make them doubt the bible in other areas.
I am unclear why you don’t see their tactic for what it is. Nor how effective it’s been because we haven’t had people who could respond to someone who’s been exposed to it, by a college prof who has the intent on destroying as many Christian kids’ faith as they possibly can.
But how do you explain away scientific evidence that supports "the concept of billions of years"? For example, there are quasars out in space that are more than 20 billion light years away--that is, it took more than 20 billion years for their light to reach Earth.
