Atheists/agnostics are not responsible for scientific progress. In atheist nations such as the Soviet Union and Communist China, science lags far behind. Although some scientists foolishly choose to become atheists, their successes are only because they were educated in societies that had a religious foundation.
Not to mention the incredible Jewish contribution to science. Why are Jews so smart? Are they genetically superior? Of course not! It's because of the Torah way of life that instills in them the thirst for knowledge.
Scientists who Believed in God. (mentions Catholic Churh)
Nicholas Copernicus (1473-1543)
Copernicus was the Polish astronomer who put forward the first mathematically based system of planets going around the sun. He attended various European universities, and became a Canon in the Catholic church in 1497. His new system was actually first presented in the Vatican gardens in 1533 before Pope Clement VII who approved, and urged Copernicus to publish it around this time. Copernicus was never under any threat of religious persecution - and was urged to publish both by Catholic Bishop Guise, Cardinal Schonberg, and the Protestant Professor George Rheticus. Copernicus referred sometimes to God in his works, and did not see his system as in conflict with the Bible.
Sir Francis Bacon (1561-1627)
Bacon was a philosopher who is known for establishing the scientific method of inquiry based on experimentation and inductive reasoning. In De Interpretatione Naturae Prooemium, Bacon established his goals as being the discovery of truth, service to his country, and service to the church. Although his work was based upon experimentation and reasoning, he rejected atheism as being the result of insufficient depth of philosophy, stating, "It is true, that a little philosophy inclineth man’s mind to atheism, but depth in philosophy bringeth men's minds about to religion; for while the mind of man looketh upon second causes scattered, it may sometimes rest in them, and go no further; but when it beholdeth the chain of them confederate, and linked together, it must needs fly to Providence and Deity."
