A number of religions tend to have points where there is splinters from their belief systems where different interpretations of the same thing causes conflictions or from "leaders" not being the person people would have chosen to lead a particular group creating a civil dispute.
Further to this matter was Ancient Romes (Emperor Constantine) attempt to absorb other religions and cultures and attempt to re-write them to one religion. Why it was done? It was likely just politics, making it simpler to try and keep the many annexed provinces from having internal feuds based upon beliefs, where if one religion was treated well and another poorly it wouldn't result in civil unrest or war. As you can tell though, it didn't exactly work out well as the many different cultures did not want to adopt such changes.
It did lead to Catholicism though (and centuries of Tarriffs sent to Rome) and that lead to Protestantism due to Henry VIII's need for a male heir.
Unfortunately for this reason Religion is never something that we are going to be rid of although it would actually be difficult to imagine a world without it.
I like the approach of identifying the origin of religious thought and points of diversion.
We can know man began by humanizing nature to convey stories important to their survival, so a pile of large rocks near a source of water, becomes the three sisters. This is done because we remember best information that is stories about humans. We still do this today by naming our cars or computers and talking about their personalities. In an office where people share machines, this can be an important way to transmit information about a machine's quirks.
I like best the original story of Adam and Eve that was written in cuneiform. In cuneiform, Eden means "uncultivated plain" and Adam means "settlement on the plain", Eve is the lady who makes live created from Adams rib, but in the original story she is a goddess speicalized in healing ribs.
Now let us look at the science. Eden where a river went out to water a garden, and then parted and became four rivers. Geologists have identified this as a region in Iran but two of the rivers dried up and could not found before modern technology. Geologists also know this area experienced a long drought. Now back to our story.
The river flooded and ate a goddess's plants. She was so angry she cursed the river to death and the river almost died, but a fox was able to convince the goddess to let the river to live. As part of the deal, she made man and woman from mud and breathed life into them, so they could help the river stay in its banks. Simple enough, use science to determine what happened.

But there is a catch...
If you came from Egypt with the religion of Amenhotep the story is believable, except you know there is only one god. Solution, correct the story about a flood and drought and a return to normal weather and cultivating the land. After all, it is obvious Ra is the only God. The archives of Egypt say so.
We might want to understand what developing civilizations had to do with the increase of gods.

Again we can look at ourselves and the study of atoms, we are naming more and more parts that are discovered to make up atoms. I am no more sure of all these parts than any Egyptian could be sure of all their gods. What happened was the original cause of these stories was forgotten, and man moved on to needing to understand their increasingly complex bureaucracies and civilizations, so they started naming new gods for each newly recognized concept. Like we are naming the parts of atoms today. Many gods who interact with each other results in a very rapid increase of concepts, and eventually this meant having so many gods, the whole belief system began falling apart. Like Rome was falling apart with too many myths in an expanding empire, requiring a unified theory. Egypt also had this problem, resulting in searching the archives for the true god and coming with Ra. But the old priest hood crushed the new religion of one god, and those committed to the one god, fled to Ur, a city that was once a Sumerian city, and eagarly they studied the archives in the ruins of Sumer, realizing as we do, in the far past was the pure truth.
As all holy books were writing, corrections to the stories were made. Rome pulled all the stories together using the Roman Law of Nature rule. This was a legal tool when settling legal problems between people from different city states with different laws. The object is to take what is common in the different legal systems and come to a decision. But this culturally biased religion did not satisfy the Arabs. At the time of Mohammed Christians and Jews were living with them, and obviously these people worshipping the God of Abraham did not agree about Jesus and what is required to be in god's good graces, and equally obvious the diverse Arab tribes needed tp be unifying so Mohammed corrected the stories once again.
Now know if you are male and are not circumcised, you do not have the benefit of a covenant with the God of Abraham and you better rush out and get circumcised right away. God really cares about such things.
He also enjoys the smell of burning flesh, so you better sacrifice your best lamb immediately.
Anyone into using science to check biblical truth? Drop the argument that God does not exist and pick up the argument about all the different things religious people say that can or can not be true. To we have to be saved by Jesus to be moral, or we can use reason to be moral?
