Diamonds formed only under pressure. What about more than 10 kilometers of water above them. That is enormous power and weight. It is all in the Bible, why not seriously invest this in stead of saying that the Bible is not true.

Pressure of about more than 10 kilometers of water is far too low to form diamonds. Temperature about 1000 °C is necessaty as well.

I dont read the original paper. I think if the ages of the diamonds are reliable is the key issue as mentioned by one geologist.And if these ages are reliable, why these diamonds can not form as the whole earth was in the molten state. I guess this may happen at the extreme pressue condition, although the temperature is also quite high.
