I don't believe that any other intelligent creatures visit us. I just don't think its very possible considering the limits of technology, time, and space. It would take at a minimum of traveling at the speed of light for hundreds of years to be able to make it to earth from another planet that is capable of supporting life. There may be intelligent life out there somewhere but I don't think we/they will ever make it to these planets. Unless they figured out a short cut such as the worm hole or bending space/time fabric theories I just don't think it will ever be possible
well with our technology we couldnt travel anyplace, but im sure their are civilizations out there a thousand times older then our civilization and they just might have the technology to travel light years or through wormholes,
I mean we are in our infancy as a civilization, but imagine the technology we'll have in just another 1,000 years. the Technology we have now would blow the minds of people just 75-100 years ago.
I most defiantly think other beings who are more advanced can travel through space in the blink of an eye.
