OK Christians. your chance. Convince me of God.

Another argument in Quran is this:

1) If it were from other then God, people would find in it much contradictions.
2) People haven't found contradictions.
3) Therefore it is from God.

A valid argument, but I would say both premise 1 and 2 is definitely wrong.

LOL, no, it isn't.

Valid doesn't mean sound.

For example

If I eat oranges, it means I am a dog.
I eat oranges.
Therefore I am a dog.

Is a valid argument but it's not sound.

The argument is valid:

(a) Book From God
(b) people would find in book Contradictions

Not A -> B
Not B
Therefore A.

Not A -> B = Not B -> A

It's not sound argument, but it's a valid argument.
