People on both sides of the debate about the existence of God occasionally cite the views of Albert Einstein as providing support for their side. This is tricky business since Einstein's views were unorthodox. He was not a theist who believed in a personal God nor was he an atheist who discarded the idea of God altogether.
He was, in fact, a good example of a modern deist who believed that there is some force or intellect which established the moral and physical laws of the universe but which does not interfere with those laws in any way. Einstein did not believe in life after death and did not believe that humans possessed free will, although he did believe that we have to live as if we are free.
The current issue of Time has an interesting column by Walter Isaacson on Einstein's religion which explores these beliefs in more detail. It's worth a read for those curious as to what, exactly, Einstein thought about God.
