Well anything that cannot be currently explained by science gets the label random, or it gets put on a shelf until an explanation can be made.
This leads us to an incomplete picture of how everything really works. Also since no theory can ever really be proven, we can just keep relying on overwelming evidence that can be easily explain so that our feble minds can coop with it.
Yes this is the same logic they will use to explain away God. We have answers, but not all of them, but we will, just you wait and see.
"I cannot believe in God, I have no choice"
