The Oral Torah is collected in 20 volumes of Talmud, which take up a shit-ton of space on a library shelf. I would recommend reading an encyclopedia entry on the age of the Jews.
As for the comment about the Muslims, do note that Jews are capable of change. We no longer execute for adultery, and the like. Muslims still LIVE in the Seventh Century. We refer to the Torah as the basis of legislation, but amend it as necessary to reflect life in the modern world, much as the United States no longer considers the Negro 3/5 of a person, or permits slavery, etc etc, but has amended its constitution to reflect changes in life in the modern age.
As far as keeping Oral Torah straight, its harder than a non-Jew thinks. Just because its been written down, in many cases, no firm decisions have been decided on its issues. They continued to be debated today. In some cases, firm decisions have been made, but in many, different decisions are made when the situation comes up depending on the circumstances.
Since human beings, and civilisations, do not always operate logically, application of the rules of logic cannot always apply. By that standard, they would have given up the search for the first three dynasties of China since for many, many years they had found NOTHING. But they did not, and eventually, the research paid off.
At present, I must sign off. Have a pleasant day, people.
When you see that the Written Torah is backed by the Oral Torah

I hope you notice the contradiction here.
So what you're saying is that you DON'T have the same culture as 4,500 years ago, the Oral Torah is debated and thus is not valid evidence of anything, and the written Torah doesn't back up the Oral in all places, giving that little evidence.
Also, didn't Egyptian Myth endure for quite a few thousand years?
Greek Mythology still persist to this very day. Though it was believed to be true for a few thousand years as well.
And isn't Hinduism the oldest religion in the world?
I submit that people do invent religions that persist for thousands of years. People are, after all, easily led.
