Zakir never responded when I said that, in the past, Christians were the most quickly growing religion, not Islam.
I also said that Islam, like Christianity, will eventually decline, and that rate of conversion has no bearing on truth.
Zakir's arguments, which I collected both from his words and by visiting the links he posted. I have not used the exact words, as I don't have enough space or time.
1. The Koran is so well written, it must have been either written by a god or inspired by a god.
Answer: People can write pretty damn well. Anyway, none of the English translations sounded very good to me. This point is based on nothing more than ridiculous bias.
2. Muhammed was completely honest, and there were other witnesses to events in the Koran.
Answer: Prove to me that Muhammed was completely honest, (you can't) and this point will be valid. Saying that he was completely honest because of a god is not proof- because it is circular logic at that point.
Also, aliens have had many witnesses, as have many Christian miracles. DO you believe in both the Christian god and aliens?
3. 1.8 billion people follow Islam, so it must be true.
Answer: There are 2.2 billion Christians. Are they all wrong?

BTW, I looked at all your links on why the moon really split. Two of them link to amateur, non-scientific opinion pages, and one to a forum. None are actual evidence.
