Is the Earth the only planet and place, where the life is? Or is there another planet or place in our galaxy or in our universe or in another universe, where the another life is?
There may be another life in the universe, the development of this life can be higher than ours. If their development is better, their technologies are probably betters and then they are able to do things, we may think are not able to do. Maybe their knowledge would be valuable for use, maybe not.
Maybe some aliens are just watching while I am writing this text. We do not know. They may have a very good technology.
