Hello I am Stephen Hawking and I was a theoretical physicist, cosmologist, and author and I think success in creating AI would be the biggest event in human history or it might also be the last, unless we learn how to avoid the risks. I believe if aliens visit us, the outcome would be much as when Columbus landed in America, which didn't turn out well for the Native Americans and I am an atheist and is no God. No one created the universe and no one directs our fate
