  1. No, we won't if we have very narrow definition of life. And those who think that viruses are not life, have very narrow definition. What if alien life will be more like viruses, rather than like cellular life on Earth? What if they will have protein membrane rather than lipid one? What if they will reproduce by disassembling and then re-assembling, like viruses do? We will not see that kind of alien life as life at all, if we keep denying the fact that we already know 2 very different types of life here on Earth: cellular life and non-cellular life. #VirusesAreAlive
