It is not clear who said it, not necessarily a celebrity, but a conclusion drawn by future generations based on the experience of cattle people. In fact, the greatest scientist known eventually led to idealism. Such as Einstein and Newton. This is mainly because the top figures in various disciplines are thinking about the most essential problems such as human beings, spirit, matter and the universe, and these problems will naturally rise to the height of philosophy. But these geniuses will eventually find that many things and laws are too perfect to be reasonably explained unless a "God" arranges them in advance, so they have to believe in God, hehe.
