deGrasse's observation was that when a scientist reaches a point where he can't explain, or understand something often he attributes it to God... And then years later someone else find it's explanation, until he stumbles onto the next problem.

It's all good. I gues it's okay to put God where your knowledge limits you, or the current more wide one, but just don't spread it that it's because of God.

e.g. God is "what we don't understand"
