Angels vs Viruses. About 20 years ago I read an interesting theory about how theoretical aliens would look to us if we happen to find them. The theory was that the assuming that there is life other than earth's in the universe, the probability of it being within ±10,000 years of current human development (i.e being similar to us now ± 10,000 years) is very very small. Most likely, life outside the earth will be 20k, 30k or even 50k, or more years in the future technologically, socially and medically advanced. Think about, how a human now would look like to a human 50,000 years ago. Or how humanity would look like in 50,000 years. For all I know, we will be able to replace every organ (lab tissue growing), live for a LONG time (Hyperbaric oxygen therapy, metformin) and other unimaginable things. So, if we encountered "space traveling" aliens, their frame of reference would be completely out of our understanding.
