Breaking into a system or exposing its weaknesses is a good thing because truth and knowledge must win out.
No one really knows what I'm really like, and you won't unless you spend a day with me, or if you're my friend. No one ever knows what anyone is really like. Read all the interviews you want on them, it's just the media talking and you can't really get to know someone that way, obviously.
No planet is more earth-like than Earth itself, so if life really does pop up readily in earth-like conditions, then surely it should have arisen many times right here on our home planet? And how do we know it didn't? The truth is, nobody has looked.
