the only thing I'm saying is that there isn't going to be an abundance of life in the universe..... life's a pretty delicate system so you would need the exact conditions wee have on earth.... this means that any aliens out there will be pretty much identical to us (unless they're in an evolutionary stage wee haven't reached yet) and the percentage of planets which will actually harbor life will be virtually non existent so there is no need for anyone on earth to go into too much thought about it..... any existing beings out there probably would have given up on these concepts to be able to advance their own planets...... I'm saying this in the same way that i would say that religion has slowed man's advancement. wee haven't even begun to properly explore our own solar system yet so wee shouldn't bother dwelling on the thought that there could be life out there because it is probably a very insignificant amount.....
