[quasque]

It's a poorly argued essay.

The author starts from an assumption that the Bible is true and cherry-picks evidence in an attempt to support that, choosing the interpretation (or misinterpretation) that best fits into his pre-existing biases.

Not convincing unless one has already been indoctrinated into the belief that everything is 'God-given', rather than being more open-minded and inquisitive about the nature of the world.
