0% in my opinion. Time travel into the past creates impossible paradoxes. In the classic example, if you went into the past and killed your grandfather, you prevent your own birth and therefore would’t be able to kill him in the first place. And Stephen Hawking has said if time travel is possible, where are all the tourists from the future? He also demonstated in one of his books (a brief history of time maybe?) that using time travel you could make a bomb that could produce infite energy, destroying the universe. It uses a wormhole that copies a single photon infinite numbers of time in an instant. Time doesn’t really have a backward and a forward anyway, it’s just a way to measure change.
Well, obviously, if you set out to kill your grandfather, it would turn out that you weren't able to do so - perhaps you were hit by a bus on the way to his house and buried unidentified in a pauper's grave.

Agreed. Of all the theories to explain the unexplained, this is the one most deserving of a tin foil hat and for the very reasons you noted.
There are explanations for mysterious events, we just don't know them yet and may never know some. I don't rule out alien life but do "time travel"
> Time travel into the past creates impossible paradoxes.
They very notion of “time travel” presupposes that time
is something (a “4th dimension”) that exists independently.
It may be just a human concept for quantifying motion.
The past is not still going on somewhen.
It is over.
