First, what does "apparent design" mean? In practice, it involves living systems in the first place (fewer people talk about the "apparent design" of canyons or galactic nebulae, or subatomic particle fission tracks), and that their components do all sorts of neat stuff (like metabolizing food, and parasitizing the brains of animals).
At no time in my life did I have a belief in the reality of any gods (which I imagine includes whatever one you believe in), so it is not a matter of not believing "anymore."
Jim Downard offers his own script for what an atheist might say as an invocation, something fair and honest that doesn't make "presumptions on the religious convictions of those assembled."
Is there any good reason to think any particular god, currently worshiped or not, explains the data stream at all, let alone better than a naturalistic framework?
