Muslims, why would an all knowing Allah, who created the universe with all its wonders, want Earthlings to follow ancient desert laws?

The religion was founded in Arabia, so Mohammed and his followers knew nothing about other parts of the world, other customs, other technologies, etc. Even today, Islam does not do a good job reinterpreting its teachings to fit the modern world and today's lifestyle.

Islam is not only for desert people. It is for whole of humanity and it’s not ancient either. It is the most recent of Abrahimic faiths. Judaism is a tribal desert cult with ancient barbaric laws. Anyone who reads the Torah can see that. Yahweh tells Jews to slaughter anyone who is not Jew even women and children. Yahwehs covenant was only with the Israelites. So non Jews are fair game and Jews can oppress and mass slaughter goyim and they have thumbs up from Yahweh. Israel is applying these tribal laws when they oppress and indiscriminately kill Palestinians.

One of the ancient dessert laws said that man must live the life of seclusion by becoming priest and monk hood.

Revenging was allow among the different tribes of dessert people

Believing in worshipping Idols and believing that god had a son

Drinking ,gambling, fornication ,adultery were allowed among the desert people.

So on so forth

I dont suppose you realize that Moses and Jesus came from the exact same desert region and proposed the exact same laws..

Islam is a lie. Jesus is god.

"I am the way, the truth, and the life. No one comes to the Father except through Me" John 14:6

False moon god doesn't exsist. There's no heaven for Mudslimes.

Allah gave the Qur'an supported by hadiths as life guide not only for Arabs but for whole people on this earth so it is not a desert law so it is logic and nessesary
