I guess it is a natural thing for humans to wonder what is out in space. I do not how long man has thought that there are little green men or other life forms out there. It was a little before my time (I would have been in the single digits still), but “B”science fiction movies in the 1950s possibly began the trend in my lifetime. The government and NASA apparently in the 40s and 50s were collaborating to be the first humans in space. We had to beat the “Ruskies”. Then, in my starting remembrance, Lost In Space came to television and then Star Trek. I sort of think it was at this point that mens’ imaginations began to run wild. I think it parallels nicely with the tower of Babel in Genesis 11. The whole world decided together that they would build a tower that would reach up to God. God watched for awhile, and then just confused them so much with languages that they all had to stop and go their separate ways. They actually imagined that they could do it. I can just see in Heaven, the angels still bring this up at coffee breaks and everyone up there is swapping stories about those crazy mortals.
