Montana Tech. Professor says ufo's are time machines from the future....

Anythings possible more like dimensional travellers outside of what we experience as 'time'. Grey aliens or any aliens (no discrimination here!) could be human upgrades from a future, dimension or time line etc. Humans/earth dwellers seem to have been taller, smaller, now we seem to be becoming infertile & genderless. We will have to be created, tweaked & experimented in labs (Egyptian hieroglyphs of human eagle/ snake hybrids?) to what end who knows! grey, lizard like, maybe all aliens are just versions of us!
