Here I thought this was something that everyone knew.
Please read my posts. Not everyone knows the functions of the brain. The majority of Muslims are illiterates. 800 million Muslims out of 1.4 billion are uneducated (6 out of 10 cannot read). How can they be expected to know grade 6 science.
Now Britedream claims the educated Muslims get their science from the Quran. And he gave us a good example the pain is in the skin according to the Quran. According to the Quran if you burn the skin they will feel the punishment. But most Islamists don't know that because they are illiterate and cannot read the Quran. That is why they mistakenly cut the heads off their victims when they should be burning their skin to inflict punishment.
