It is very likely that at some point in the near future we will develop nanotechnology which will change everything. Humans will eventually all wear nanosuits that will protect us from the environment, recycle bodily waste, augment our strength etcetera, it is feasible to imagine we will be fitted with a suit at birth and never have cause to take it off.

Given time to evolve our bodies will become smaller while maintaining our head size to hold our brain, eventually we would end up looking like the little green men we are familiar with.

So was Roswell a time travelling future human? Are abductions our future selves looking for or harvesting something that we currently have that they have lost along the way?

As good a theory as any, perhaps if it does indeed become possible to travel backwards through time, even likely that we'd want to visit our ancestors sooner or later.
But...well...just a hypothetical i guess.

If we were comming back in time as aliens, couldn't we forsee the problems with the world and keep returning to right them? That would seem the thing to do,unless only certain "aliens" were allowed to posess this ability,such as the heads of government. HEY! ,...wait a minute,isn't that whats going on here in our world?

Very interesting I also have the view that our future ancestors are working on time travel early years such as Roswell thats when we started to advance in leaps such as computers and new techs ect,,,
Way too fast this in turn has effected there time. So if they come back and change things in our time it will effect there time and so on. Also in the future we have changed our body to suit our enviroment that's why they are coming back to gather dna from ancestor decendents. To change back to what they have lost the human strain geneticts as all in the future are made in a lab. There is no need for sex to breed so there is no male or female genders all are the same there is no race wars as all are the same. There is one world religion called "science" there are only thousands not millions or billions of people there is no free thinking or freedom, and there race needs new dna because the strain is getting weaker every time it is cloned causing up to 80% failed cloneing...... Wow what a future, glad I wont be there.

hmm..this is a good one, i like it. it is very possible that aliens our actually not beings from across the universe but us, evolved and from coming from the future through some kind of time travel project??

interesting, but it would take a long time for us to evolve (again?..we're evolved from apes right???) into that. and if we did evolve again our brain power would most likely be much more than now, BUT will we ever conquer time travel? ......who knows man..who knows...

Have any of you had weird dreams? I woke up one night and I was turned around in my bed and the covers weren't messed up and I have scars and I don't remember getting them either.

It seems that we have a paradox!

I've often wondered whether humans from the future were visiting the past and whether these humans were now so evolved that they do not look like us, but like the whithered Grays... It's a possibility that was explored in one of my favorite books called THE HUMAN FACTOR by AJ DiChiara. It's a great read for anyone interested in a fast-paced fiction novel. It would be nice to know that the human race can survive the 21st century and reach a point of peace and prosperity.

Oh my God Yes this is what I Feel and Think we are a Carbon copy of the past and yes they come to us for what you say. But, they can't change the past because it will affect their Present. That's why we have deja vu, we lived the same life over and over again. Please tell me if you feel the same. I can't stop thinking about it. Technology is advancing very Fast and I think the government knows the Secret about our existence in this world. In the U.S. now they what to get Rid of the analog Signal All together and they say is to sale it to Cell phone companies. What is the Secret with the Analog Signal that The US Government wants to get Rid of it ...... Think about it, why force Digital into the United States before the end of 2009?

Nanotech is already here. For the people that Don't know, we have body Suits that tell us our blood Pressure and temperature. They just have not been released to the public. More tests are taking place with more features like immune Body Suit. Yes, resistant to particular infections or toxins and can diagnose a patient of what problems he/she is having or what they might die from. It will study you're body and it will tell you what is good for you and what is not.
