Being religious and having a scientific mind are not mutually exclusive. There are uncountable examples of people who have made contributions to science who were also religious. I highly doubt that 100% of the scientists at CERN are atheists, although I have done no reading to confirm that.
Edit: two minutes of googling:

My cheeky highlight:
"Max Planck: He won the 1918 Nobel Prize in Physics and is considered the founder of Quantum mechanics. He had been raised an observant Lutheran and was an elder in his church from 1920 to his death. In 1937 he delivered the lecture, "Religion and Natural Science", stating that both religion and science require a belief in God.[note 7][108]"
