In my us history class, my teacher digressed from the topic on how native americans were killed by disease brought by white settlers. Then i thought about aliens for some random reason, i day dream a lot . Well anyways, my hypothesis is that we may not meet aliens for another few centuries because like the white settlers that brought disease, aliens might(more likely will) have diseases that are likely transmitable to our planet and would majorly effect the eco system. Or, we may have a disease that would kill them in mass and they dont like that idea. So im thinking will probably never meet aliens in this lifetime or the next few.
Make sense? debate?
