Nunovalente #2, You said "Yet their faith in nature no different to the theists in God."
Maybe the ideas about ancient creatures are based (in part) on the fossil record, so it is not really (only) faith.
When we find God bones in the fossil record we can use the same process to speculate about God. Until then we have nothing material that relates to God. We have many different ideas and claims about a non-material God, but God is conjecture, a plot device to explain some of the unknown.
To call aTheism a delusion is to mis-represent the word aTheism - aTheism is the "a" (lack of) of an "ism" but is not an "ism" itself.
As I said, its mere speculation. A few bones, and from it we have incredibly details images of skin, moving pictures, sounds, food, behaviour, all played out in Hollywood style, and the public lap it up as if its all absolutely true. Talk about evidence.
Once you apply what you believe (from Fossil records or whatever) and put it into action, your expressing it by faith. You do not know. Your just confident about unseen facts. This is deemed acceptable.
Yet how quickly the biblical narrative is dismissed, regardless of the evidence, when all of those who drafted it were real people, with real testimonies, of real events.
None of the biblical narrative indicates God has bones. So no point looking for them. Other than Jesus bones, but we won't find them either.
