Genuine question Harry, why are you so opposed to such thoughts? You only have to scratch the surface of quantum physics or string theory to appreciate that not only is it possible it’s actually probable.
I'm quite open to the idea there is other life in the universe. Statistically it is 'odds on'.
However, that is a million miles away from considering it likely they are already here, flitting about obscure deserts in oddly-shaped vehicles, or secretly infiltrating our governments in order to manipulate the human trajectory through the spacetime continuum.
