I didn't say I believe in 'psychic'/ESP powers. I don't believe in them. But I am open minded about their possible existence. I thus did not replace belief in the supernatural with belief in 'psychic'/ESP powers. Furthermore, I became open minded about the possibility of 'psychic'/ESP powers more than 10 years before I became an atheistic naturalist. I became open minded about the possibility of 'psychic'/ESP powers while I was still a believing JW, and it was largely as a result of watching documentaries on TV about such. However I think it is unlikely that any 'psychic'/ESP powers exist since their existence has never been scientifically conclusively demonstrated to exist. I have books by Victor Stenger in which he says scientific experiments attempting to demonstrate ESP have failed. But a number of scientists continue to do experiments to see if some form of ESP exists to some degree. Some scientific peer reviewed journal articles have reported positive results of certain types of ESP (including short-term precognition), but other scientists were unable to repeat the results. In some cases flaws were found in the way the experiment was done and/or in the way the data was processed. In regards to whether I want to believe in ESP, I do want to have ESP abilities.
Einstein, as represented in the block theory of the universe, said that the past, present, and future co-exist. If that scientific idea is true, then it seems that it might be possible for people know their future much the same way they remember their past. Furthermore, the scientific idea about the possibility of time travel includes the idea that the past still exists (otherwise how could someone travel to the past?) and the idea that the future always exists (otherwise how could someone travel to the future?).
