I can go to France, I can see and touch snow, I have a cat that walks on my keyboard. No one has to convince me with supernatural mumbo jumbo that these things exist and we can all objectively agree they do. That fact that when you say the word "cat" people all tend to think of a similar image tells you this. You emotions that you associate with any of these things are irrelevant.
Can you do any of these things with a god?
Yes this is a materialist view point but this is a material world and all the things you mentioned are material things or at least concepts about material things. A country after all is nothing but a concept applied to an expanse of real estate.
You can point to things we don't understand and come to the conclusion that because we can't understand them that there must be some supernatural agent that is the cause but that assumes that humans are actually capable of understanding absolutely everything and I do not think that is true.
