JP was in our military and said he saw people (soldiers? researchers?) coming out of portals wearing clothing from past eras. They go into the past to supposedly do research about timelines and probably people... Time travel definitely exists. Certain years are very important for information and research. If you think this is weird but want to check it out I think he is on Youtube now. Cheers to this post. I bought that John Titor book mentioned... Thank you!
