What needs justification are your assertions (#40; #42; #44) that a god is somehow present in or behind the garden. Not merely that such a thing exists - any fool can simply assert that, and frequently do - but the means by which this is known.
I'm all ears.
What needs justification are Adams assertions. If philosophical as you claim some justification should be forthcoming but here you are assiduously trying to avoid the prospect.
Why should empiricism, physicalism, naturalism etc be immune from any challenge to justify them?
regarding Adams and Hitchens, were they around today I think they would be astounded at the retreat of their spawn from a committed antitheism, naturalism, empiricism and scientism.
