I like to think of The Big Bang Theory (the tv show) when thinking of time travel. A character mentions that if his friend is still working on this time machine which he states "if I ever did invent one I would just travel back in time to give it to myself so I wouldn't have to build it in the first place", which makes me think that if we did invent time travel in the future that by now someone will have came back from the future to give us time travel (unless as stated by someone else, backwards time travel isn't possible which would not only cancel out that thought but also aliens being future us).
Or even if they didn't come back to give us a time machine or the knowledge, there would at least be rogue people that go back and prevent certain things from happening (assassinations, wars, terror attacks, etc). I guess one could argue that by some people NOT being assassinated, some wars NOT happening and other attacks never coming to light is proof that we've time traveled back, but I'm not going for it.
Personally I don't think aliens are time travelers, rather they are just other beings.
"Would it be out of sink to say that the visitors are not from another planet but from a different time. Future evolved humans coming back to the past to see there evolution and visit the earth when it was still blue. Abductions are not just for info but for cures to future diseases. Think of it like a trip to the rain forest. The beautiful sights, the future cures and unstoppable destruction of. If everything started with a big bang then our matter and everything started at the beginning. No other being could have enough of a head start to be ahead of our progress (at least not to the point of multi-light speeds and universal mapping). "

Time Travel, I read something the other day I was not aware of regarding Einstein's theory which basically said his theory include forward time travel but cannot preclude reverse time travel.
If his theory of Relativity holds fast in future then reverse time travel cannot exist. Interesting in ufological terms.

It's entirely possible, especially so since it is know to be at least scientifically possible to time travel, even if at our current tech levels, time travel would seem to be highly unlikely.
But don't fall into the trap of thinking everything is linear...just because a Human existence is measured in a linear 'lifespan', a variable period of time, or an interval measuring the amount of time that passes between birth to death - doesn't mean that development of Human culture, societies, technological progress is always going to be a linear A - B - C affair.
A scenario to explain Humans 'evolving' into the 'greys', and how their various attributes formed could be one such example of a non-linear development.
Imagine a nuclear war, where most life on Earth is destroyed. There are survivors here and there, mostly the wealthy or powerful, or their military protectors hiding out in their bunkers.
They might survive that way for generations, until their technology begins to fail...power for filtration systems goes offline, reactors fail, blow up or are attacked by rival survivor groups / clans.
Reduced to a troglodyte existence, without significant technology, mankind is forced to adapt to the conditions they find themselves in...and over time, living in the dimly lit underground, their eyes would evolve to be larger, to allow more light into the retina. Their grey, pallid skin would also be due to their never being able to see the Sun.
The seeping radiation would affect their bodies too, especially over generations, possibly causing their enlarged heads and stunted bodies.
Then, over time solutions for their problems were gradually engineered. At last able to emerge into the above ground world once more, their societies were rebuilt, again over many generations and through trial and error (having only oral folk memories and local legends of the time when their ancestors walked freely upon the surface of the Earth and the technological marvels they once possessed..there were stories of their ancestors travelling through the air and beyond the skies, massive metal craft as large as a city that could cross entire oceans without stopping (many of which were scoffed at as pure fantasy thinking).
They would gradually bring themselves up to technological levels once only spoken of in folklore, and then go beyond those levels, until they reach the stage of progress that allowed them mastery of the skies, seas and space..and time.
They could very well be our far, far, far, FAR future offspring, who are doing anthropological studies..studying us, their ancient ancestors.
How strange we must all look to them...as from their point of view, we 'modern Humans' are ancient, primitive, dribbling idiot Neanderthals like creatures...interesting, but damned ugly.
