Dawkins wants to investigate the scientific validity of religion by examining it using scientific methods. When this is done, religion falls apart as a useful device except as a device
for interpreting human behavior.

Not true Strings my dear friend, there are many many top scientists that are men of faith because their scientific views lead them to the existence of God. On cannot make general statements about scientists. For everyone that says no there is another that says yes. It is impossible to prove of disprove hence it is simply down to faith. Likewise someone said no one can claim atheism as a faith since it is like saying not collecting stamps is a hobby. Not true, I know for a fact stamps exist. However since it is impossible to determine the existence of God then it is simply a belief system. Hence a faith ..

my take anyway and it is not meaning to offend anyone
