Some Christians are too quick to pick up on scientific discoveries and say they support the Judeo-Christian accounts, when if they had read the paper in question, they'd know better, and not look like fools in the eyes of those who don't believe in God, and thus damage the cause of Christ.
I am a Christian, but I don't want us to look like fools by claiming hydrated silicate rock is the same as "fountains of the great deep".
