This post is for individuals who believe there is a universal god, creator, divinity or consciousness. Therefore we will skip the arguments of the creator and can argue about sending messengers.
If you want to understand some attributes of this creator, what is better than looking at his creation.
I see a vast, great and majestic universe far beyond my humble comprehension and intelligence. I see a majestic complexity and intelligent design in the creation of living beings from the microscopic genetic makeup up to the macroscopic phenotypic morphology.
I see this as a great performance beyond words but for sake of simplicity, I call it "performance in creation".
I will compare that to the "Performance in delivery of his/her/it message"
Now let see schools that claims the creator sent messengers with books and religions. I am mainly pointing towards Abrahamic religions given my background more precisely Islam.
The creator who is omnipotent, omniscience has a throne (regardless how you interpret throne) and he send a man with a book (regardless of how muslims think Bible is like the Torah and Quran a revelation) just like naive human projections of a king who send a delegate(s) with a message.
This creator knows that people will corrupt and twist his words yet he can not find a better way.
This creator is dependent on narrators and generations to pass on his word uncorrupted and the exact same interpretations not other imaginable or fancy interpretations.
This creators sends too many prophets and messengers to small nation of Israel meanwhile he knows that he kind of forgot about Arabs who are praying to Idols over many centuries.
This creators thinks Israel deserve a long list of prophets and messengers but other nations like Egyptians, Africans, Arabs, Babylonians, Persians, Indians, Chineses, Europeans (Greeks, Roman, Germanic, Celts,...) natives from other continents meanwhile need one or two messengers and can practice Voodoo and worships many deities and spirits until he finish with the Israel first.
The Creator is obsessed with Israel that he has to mention them in Torah, Bible and Quran. So obsessed that he choose them initially then curse them 9 times in Quran like an angry boyfriend.
The creator probably weak in geography and spacial-temporal dynamic of people that he concentrates most of his efforts in Israel and later in Arabia.
This creator is so omnipotent and omniscience being aware that human psychology, science, technology, morals, philosophy evolves overtime and require newer prophets and messengers to stop at least chopping of each other heads between Shia and Sunni muslims each claiming the uncorrupted version of Islam, yet he decided that he will conclude the seal the prophethood and message with Mohammed of Arabia.
The creator has seen that his slave Mark Zuckerberg has created FACEBOOK better technology for delivering messages and communication. He said to hell with that, I am out !
I can safely conclude that there is a vast inconsistency between the performance of creation and the performance of communication and delivering a message. This vast inconsistency tells me that the THE ENTITY WHICH CREATED THE UNIVERSE CAN NOT BE THE SAME AS THAT OF ABRAHAMIC RELIGION.
