But you’ve posted that before? Anyway, Einstein definitely did not say that because that’s not how he talked. He was a gentle and soft spoken person. Hated being with humans and spent most of his time alone. Also, he would never curse. This was created by someone or some people who didn’t agree with some of the things Einstein said.
Another thing is, some of Einstein’s quotes are very famous like “I am convinced that He (God) does not play dice” or “Reality is merely an illusion, albeit a very persistent one” or “God is subtle but he is not malicious" as they were very controversial in his days. These comments happened when he went back and forth with some other theoretical physicists.
The other ones are just less mentioned as they didn’t get as much attention. Also, the thoughts you have at age 20, you are unlikely to have same thoughts 20 year later when you are 40 years old and so on, because by then you’ve matured far more through different experiences and as a result, you have different perspective of things. So you will see a reflection of that in many Einstein’s’ quotes. These quotes can be found not only on websites but also, in many books written by different physicists about Einstein.
