Hypothesis (please note this before replying): time travel is possible.
Once it is realised, one cannot 'die' as one can always be 'visited'. Time travel also suggests that time is on a 'loop' and thus time travel already exists as existence has no beginning.
I will throw this in also: 'UFO sightings' are not unidentified, they are just not identified at this 'moment' (unless identifying them now counts?). These 'objects' are moved by our future peers (this word works in my own context)travelling in time.
This is very messy, but rather than insulting, or patronising words, you could simply ask for a more lucid explanation and i will give it via email.
P.S. Also! Time does not exist which is exactly why we cannot travel in time and exactly why we can.
