That is not surprising.
From what I have seen they do not have any biology claims at AIG, all they do is try to undermine the naturalistic model.
What is the naturalistic model? Does it allow for the possibility or certainty of God's existence?
Philosophers and scientists (scientists can have philosophical or theological views too) do have beliefs or biases. Even the scientific method has philosophical roots or input. But from my recollection unless science is done recognizing creation and a Creator of that creation science neither approves (affirms) or denies the existence of God.
There is a difference between what is natural and what is supernatural.
The idea of an observable universe may or may not include that which some people term supernatural.
But making measurements in the natural world makes sense to me.
