Time travel - sensible?

Since the begining of civilization there has been what we would percieve as sighting of UFOs - some can be explained others cannot. A popular belief and one i subscribed to myself not too long ago was that these so called aliens who flew these UFOs where not infact aliens but time travellers from our distant or maybe soon future.

Id like to give me thoughts on it to you people, first off imagine the future ethics and morals of time travel no way they could justify time travelling, you see my view is that the slightest lil change in the past changes everything in the future - and i mean slight.

Now suppose they are doing this and thats what UFOs are, well then theyve already changed the world beyond all repair for the better or worse i dont know , but my point is all it takes to change the whole course of human kind is one person to think differently to what he she would have without seing a UFO because as you probably know that person will do something different and knock on effects, - perhaps a similar theory to the "Butterfly effect" the smallest flaps from a butterfly can produce a small enough change to cause a hurricane or tornado years in effect after.

link to that theory jamesthornton.com...

Now you see in my logic if i were to time travel i would send anyone back - id send a sattelite to record earth beginning and so on recording it all - it would have an I.A computer and so on obvious techs - and before you tell me that we would spot it and so on - lets just say our decendants arent stupid and will have built it to be stealthy and totally undetectible.

Now considering my view is that just by being here from that very moment things change - all it takes it for someone to have looked at the time traveller when in the previous time line they wouldsnt have looked and maybe bumbped into a lampost lol anyway.

Your thoughts would be nice.
If im wrong please tell me its something thats bugging me.

Feel free to relax - you can't go back in time - only forward.

Think about it and do some research at the library and I am confident you will come to the same conclusion.

The paradoxes of traveling back in time cannot be overcome without using the multiple universes theory - and if that is true then it doesn't matter (to us) anyways as it will not effect this universe.

I think time travel is like trying to make these super gravity manipulating air craft. We're trying to develope it. Not quite there yet, but possible.

I posted these links in another thread that was recently started on this topic. I think that this has been pretty much discussed to it's exhaustion point...
