Extremely low IQ, masquerading as "high IQ," I already explained to you that Islam does not get its customs from previous civilisations. It draws absolutely zero inspiration from other people, Islam is merely a revelation of what actually went down in history when it comes to things such as the supposed crucifixion of Jesus which wasn't something that actually happened. As for "muh rain dance customs" (just goes to show you're nothing but a pretentious alt-right cuck) there is nothing superstitious in Islam, every ruling outside of Qur'an and sunnah is based on logic. Stop browsing cucked stormfront-tier sites and gain actual knowledge by going to an imam.
Just goto the Imam bro! yes, that will be completely unbiased, just like i should goto Greek Priest, he'll tell me muh Orthodoxy, or Roman Priest will tell me muh Catholicism, or the Rabbi and will tell me muh Judaism, or the Swami will tell me muh Hinduism, or the Lama will tell me muh Buddihism.
You can get 1,000,000 times more knowledge if you just study everything from an outside perspective looking down, and not only study religion, but study customs and traditions and basic day to day living of all the different cultures, you can simply date each finding, and apply it to where it originates, and I can tell you now after studying Islam and pre-abrahamic religions, cultures and societies, I can tell you now Islam is not any special from previous history, you're coping with it, I can understand that, but when you remove cope and apply autistic honestmaxxing you can see the world for what it is and see where everything originated from, or at least you can go as far back as possible.
The only reason we associate certain things in history mostly Egypt/Persia/Greece/Rome because those 4 civilizations left the oldest evidence and historical information available to us. IF you want to take a specific case, such as in ancient Greece 500BC, with women not being allowed to leave their house without a male family member, and must wear veil, the only reason history associates it with originating from there is because thats where the oldest original text describing such a rule exists, it is very possible that this rule was adopted by ancient Greeks from another culture, but as far as we know, these specific 2 rules of male escorting female member outside + veil, the oldest text describing such rules occurs around 500BC in Greece:
So you have a few conclusions to make
1) Ancient Greeks took the idea from native Anatolians, who took the idea from Phoenians, who took the idea from Arab Nomads, and its just that nobody else besides Greeks wrote it down
2) During Greek Hellenic period, you saw a lot of Greek influence in Asia, a big part of west-asia and the middle-east went through a process of Hellenization, it could be that during this time period, Arab Nomads adopted Hellenic rules when it came to Women clothing (viel) for example (This is what most historians believe btw). Later Romanisation of the areas, same logic is applied, although Eastern Roman Empire (Byzantines) was ethnically majority Greeks, so it still held many Hellenistic cultural aspects from the previous period.
Historians are like 10-90 on 1/2, the most logical being 2, but there is a possibility of other cultures simply never recorded proof, so until evidence is found that show Arab Nomads originated with these rules, the origin goes to where the evidence points, and not to what any official of said religion tells you today who are obviously going to take the perspective of their own religion being the fresh, new, and completely original content.
In regards to your "muh alt right", and "muh stormfront" - if I was that, I would be of the belief that the ancient Greeks/Romans were Nordic White Ayrans, who left Southern European and moved up North, because thats the lore they've adopted as the origins of muh White People master race.
Let him cope, even though every religion is obviously a creation of mankind.
IDK why he would cope with Islam in this way.
Most Muslimcels I speak to (who are into history from unbiased perspectives) know all of this shit, its why it gets hard for them to cope with it, because you just have to remove the blinders of cope and look at evidence, and you feel like a fool. Its no different to Bluepilled Normiecels when discussing the modern sexual market. Same cope mechanism applies. Theyre afraid to take off the blindfolds as it will completely ruin their equilibrium in life, at least temporarily, until they accept the reality of the situation.
Also - I am Low IQ, but I can see trends in history and pick them up easily. If I see something happen dating 1000 years earlier, to another group claiming original content 1000 years after, you can see where it's easy to point out its not original content.
