You have never heard that God is The Ultimate Reality.
This is why I can't believe you have any knowledge of this subject. This is theology 101 stuff, and without this understanding there really isn't anything.
You are talking about a god or gods. The capitilization is not arbitrary, in English god and God are two seperate words.
In Chinese It is the difference between shen and The Tao. In Arabic it is the difference between illah and Allah.
Look, you might be a fantastic marine biologist, but you are talking about geology to a geologist. The rocks already have names, you would be better off believing me when I tell you the names rather than making up your own.
I'm talking about The Ultimate Reality, and this is what God means in the context of monotheistic theology. That is what is called God. All us monotheists agree on this. Jews, Christians, Muslims, Sikhs, Baha'ists, monotheistic Hindus, etc. I already showed you how this concept is integral to Buddhism through the words of Buddha himself, and I already just pointed out that the concept of The Tao is the same in China.
Know that I am happy to educate, but we can't really go anywhere if you are going to pretend to be knowledgeable on this subject.
For most people, the only proof required to demonstrate the existence of God is to accept what it is we are refering to when we say God. The Ultimate Reality. To take God as anything else is superstition.
