"The Big Bang Theory" was first theorized by a priest of what religious ideology?

The Big Bang theory was first theorized by a Catholic priest because the Catholic Church has a long history of supporting education and scientific inquiry. In the case of the Big Bang theory, Georges Lemaître, a Belgian Catholic priest and physicist, proposed the theory in 1927. Lemaître's religious beliefs did not hinder his pursuit of scientific knowledge; on the contrary, they inspired and motivated him to explore and understand the origins of the universe, leading to his groundbreaking theory that eventually became widely accepted in the scientific community.
