I'm questioning your main point that santa is more real than the adult God, and that it takes child like perception to believe in God.To a child there is organized santa veneration and belief everywhere too. The childhood perception of the childhood santa is exactly the same thing as the adult perception of adult santas. If you think that is not accurate I'd like to know how they are different. The adult perception of the childhood santa is certainly different than the childhood perception of the childhood santa, but that's to be expected.The adult Santa, on the other hand, is like all such entities, invisible and impossible to observe, but it becomes just as apparent as the childhood santa was at the earlier age. You would think the propensity to disbelieve in fantastic childhood stories would make adult santas rare or impossible. Interestingly that isn't the case.
Technically not true, there is evidence of organized religions and their veracity everywhere - churches, cultural artifacts, history, stories passed from person to person.
Religion is so normalized in our day to day lives that it's not surprising that people believe. If anything religion is more misleading than Santa, because we know Santa is a fun story, but religion is literally believed to be real by many, and has been for thousands of years.
Adults who take part in their organized adult santa churches and adult santa stories are perceiving just like children. The supernatural aspects of their beliefs are identical to when they were children. It's all the same, it's belief in woo. Calling it supernatural is just giving it an allegedly respectable label but it doesn't change what it is.
My main point is that as a child the childhood santa is even more real than the adult santas. The child can actually sit in Santa's lap and talk to him and Santa gets his letters and brings him gifts. Can adults do that with their gods? Do they get to sit in their laps and ask them for things and have those things appear? Not hardly.
I have a unique perspective on all this as a brother-in-law suffered brain damage at birth so that intellectually he never progressed beyond about age four. So naturally when he was in his 50s and living at home he was still utterly devoted to Santa, largely because of his mother. He only ever got past his belief when he entered a supervised group home. So I was able to watch this man in his 50s completely believing in Santa. It's identical to what adults do with their gods, their adult santas. It's exactly the same thing except that to the child there is more proof of his santa than adults have for their adult santas.
Maybe you could re-consider how difficult it is for adults to see through every day and ubiquitous cultural elements: religion, marriage, nationalism, status etc
That God isn't real, in many cases, is very hard to deduce. Many members of this forum spent years of their lives figuring it out.
