Albert Einstein was a theoretical physicist and one of the most quotable scientists of all time — being a really smart dude means that he gets appropriated by both theists and atheists. He is considered to be the "father of modern physics," and developed the theory of relativity to reconcile classical mechanics with the laws of electromagnetic and gravitational fields. He also believed in a one world government hoping that it would put an end to "an infantile sickness" known as nationalism.

“”The word God is for me nothing more than the expression and product of human weaknesses, the Bible a collection of honorable, but still primitive legends which are nevertheless pretty childish. No interpretation no matter how subtle can (for me) change this.
Facts like this haven't stopped Einstein from being the subject of a popular urban legend where he "humiliates" an atheist professor with (pretty fallacious) logic. There are also many made-up quotes floating around that are attributed to Einstein, a list of which can be found here.
