Polytheistic claims are false .
Humans assume that all contradictions are false. Any worldview that does not allow for this assumption to be rationally justified is deductively false.
Premise 1: If anyone is not the author of every aspect of creation, then his authority is insufficient to rationally guarantee the behavior of creation.
Premise 2: Under polytheism, no one is the author of every aspect of creation.
Conclusion: Therefore, under polytheism, no one has the authority to rationally guarantee the behavior of creation.
Humans assume that creation is non-contradictory. Under polytheism, there can ultimately be no reason to hold to this assumption, making it an irrational assumption.
This Argument from Reason therefore demonstrates that polytheism is deductively false.

"What is an easy way to demonstrate that open theism is false?"
Open theism is the belief that god exists, but does not know the future outcomes of human choices. Instead, he finds out about them when they happen. Open theism renders all human conclusions completely irrational. A god who does not know what the future holds clearly did not design the future. And if he did not design the future, then there is no good reason to believe that it must behave in the way he wants it to behave.
"Deut 18:18 - KJV says "bretheren": Muhammad was an Ishmaelite, therefore a bretheren. 1Jhn 4:1 says Muhammad praised Jesus without knowledge of him as Deut 18:18 says the words were put into his mouth. But if it is an Israeli prophet, why not David?"
I've merged several of your questions together, since they all seem to be referring to the same thing. That way I can address them all at once. For future reference, if you are asking a question for a specific worldview on this website, such as Christianity, please make certain to select that worldview in the drop down list on the ASK A QUESTION page, so that the wrong people are not asked the intended question. Thanks for your care in this.
"How can God be an uncaused cause?"
There is no other logical possibility. Either some things are caused, or nothing is. If nothing is caused, then I never wrote this. But I did write this, so at least some things are caused. If some things are caused, either their causing is the result of a previous cause, or it isn't. In other words, either something caused it to cause, or nothing caused it to cause.
"If god is perfect, how did he manage to create imperfection?"
In answer, I will assume this question is referring essentially to sinful humans and fallen angels (or demons). So, rephrased, what I understand this question to be asking is how a perfect God could have created sinful people. Self-described Christians generally offer, to my knowledge, one of three answers to this. 1.
