On the other hand, those who know God (as apposed to those who simply "believe" in His existence) can be sure of many things. This is because God is never wrong. Ever. He is absolutely trustworthy in that which He says. We can therefore know absolutely about our origins, and we can know absolutely what is right and what is wrong. There is no "probably" when it comes to His immutable promises. - Ray Comfort
The above quote is typical Ray.
That kind of belief system hinders progress. There are lots of unknown yet to be discovered. The lazy system of assigning unknown to a god means there is no more need to find out the truth.
