Interstellar travel may always be an impossibility. The distances are so huge and the difficulties so enormous that we may be stuck here forever. The same may apply to other intelligences.I suppose I consider problem solving to be a horse of a different color as opposed to speculation on the unverifiable. If our current level of understanding and technology does not permit us to properly survey the universe for life, then I suggest we focus on those issues that can be addressed. If life sprung up once, could it happen again elsewhere? Sure. But if it is physically impossible for us to leave our solar system, it does not make sense to argue over it, does it? Lot's to be getting on with right here at home.
