Is it normal to believe in God

For argument's sake, let's just suppose that there was a supernatural creator of the Universe called yahweh.
Let's also suppose this creature had contacted Humans in our history, and asked them to please write the proper name down.
About 990 years later, some Germanic peoples decide to change the name of this creature.
Later they decide to give this creature a gender (male), then later still, decide to capitalize the name when it is properly not capitalized.
If you were this creature, would you
be pissed or what? And yes, that's exactly how they want me to tell you.
I'm trying to relate a message to you, that is from creatures related to yahweh. They tell me to tell you, that you are stubborn, closed-minded and disrespectful.
They ask me, to tell you to please pick up a history book, so that I might be able to convey this message to you.
There are truths in what many of you believe. Even what I believed a short time ago is not entirely correct.
