I feel, however, that there are worlds and planets out that there that are capable of housing human beings and other animals...However, us weee humans do not completely understand the ramifications of light speed type traveling nor the lack of exactness of another planet similar to our own.
We have a very looooooooooooooooooooong way to go to become space travelers...
Blind hatred, close mindedness, and jealousy will never allow humans to be the full potential Gd intended them to be.
However, there is one thing that we have done well throughout time: We can describe beauty and create beauty in so many different ways such as music, poetry, and story-telling. I don't think there are any life forms out there that are as sophisticated as we are...especially if any intelligent life makes its way over here.
I want to also add that if more intelligent life did exist out there, then they woudl have found us by now especially if the universe is billions if not trillions of years old. WE might very well be alone out there...OR we maybe the most intelligent beings which currently exist in the universe.
