A year and a half in Bangkok (as ‘Nam activity was ramping up) as a baby Christian, among mostly Buddhists, was interesting.
Buddhists have no god as we know it.
The Buddha was Sidhartha Gautama and he was "enlightened," not God. People there MADE him a deity despite his continual protestations.
Most Buddhists also have other gods to worship. The Japanese, for example, are into hero/culture worship. They had no "God" as we know either.
The Chinese had a PANTHEON of gods: garden god, kitchen god, etc., a god for everything, everywhere and all the time.
I imagine the concept (reality for me) of ONE God might be just too alien for them.
We visited Thailand back in the early-mid 1980's. We loved it. I would go back there in a New York minute. Thai food is one of my VERY favorite foods. The yummiest dessert is mango and sticky rice. :o)!!
