Did Jesus already come back?

I have entertained the scenario before that Jesus will in the clouds as specified in Acts 1:9-11.  This prophesy could be fulfilled by extra terrestrials either pretending to be the divine OR by extra terrestrials that created the prophesy in the first place OR divine beings, whatever that means.

But what if Jesus already returned?  He promised the apostles that he would return within their lifetimes and he did of course meet them, according to the New Testament, after his death.

What if all these years Christians the world over are waiting to be fooled by a group of ETs in the same way Jewish people are still waiting for the Messiah, when in actual fact, ALL prophesy has been fulfilled.  I mean if you consider the Holy Spirit to be Jesus then he has in fact already returned in the same way in which he came that he came and left  the last time.

If this is the case all these people who are waiting for the second coming could be waiting a long time. Perhaps they should use the spirit that has been left behind to work together to build a better world instead of waiting for their own version of Jesus to return.

Of course another interpretation is that the entire book was devised to confuse and separate man from each other in a Tower of Babel fashion.  Each culture given its own intepretation so that peace and oneness can never occur.

It is this authors opinion that we all need to grow up and take responsibility for our own sins and stop thinking that some poor sap takes a beating every time we have a wank or eat the biggest slice of pie.
