Faith in what? We don't have any control over nature. Even the control we think we have has been granted in such a way that we can only maintain it for a time. Then we all die, or so it seems. The real aliens are the angels. The demons are probably the spirits of the Nephilim who are mentioned in Genesis 6. Faith is in God, Who controls the angels for our good. If it wasn't this way, we would all be dead already, rather than living a life that lasts almost 100 years. The biggest and most dangerous faith failure is, to not have faith in Jesus-salvation - that God through Jesus will raise us to eternal life at the last day.
