That would be a theory where if you where to go in a straight line, you would eventually return to where you where, at a later time. But, that would not make us aliens, we came from earth, and we where born there.
Aliens are also suggested as another species then human.
If you think about it, we are so far the only known life form advanced enough for space travel. Wouldnt "aliens" look the same was we do?

I think he's referring to breaking the speed of light.
Why would aliens look the same as humans? If advanced aliens exist, I'd say it is very unlikely that they look like us. It'd require pretty much identical evolution on their part, which would probably require a planet that was pretty much identical to earth.
