Keyplus, Mibs post says it all really - and Jomifli's isn't far behind. :o)
However, moving on, you're challenging me to write a book - and you're giving me 23 years in which you do it. Now that's really funny! :o)
So, let's get this straight. Mohammed was a merchant - and a wily old merchant at that - but we won't mention the Satanic verses in detail, because that was one of his less successful ideas. Right, Mohammed was a merchant - but it's fair to say his business interests were not confined to a stall in Petticoat Lane, wouldn't you agree? If not, I suggest you read your history.
Now let's talk about common sense.
Nobody had ever heard of Islam until it was invented in the 7th century. Nevertheless, it has existed since time immemorial. This you believe.
Islam's prophets, including Jesus, and apart from Mohammed, were absolutely convinced they were Jewish, but since they lived hundreds of years before Mohammed was born, they didn't realise they were really Muslim. This you believe.
Allah turned non-believers into monkeys and pigs. This you believe.
Angels talk to people. This you believe.
Clay birds come to life and take flight. This you believe.
Mountains were created to peg the earth down. This you believe.
The moon is a lamp, producing it's own light. This you believe.
The sun revolves around the earth. This you believe.
Giving birth is easy. This you believe.
The stars were created as lamps, and as missiles to drive away demons. This you believe.
The universe was created in six days. This you believe.
The universe was created in eight days. This you believe.
I could go on, but I won't. Now talk to me about common sense.
