『Isn't trust is that you think that things will happen the way you want them or the way you think they will no matter how slim is the possibility of those things to happen?』
they do trust those scientists since most of the reasons they give are quite.. how do you say it, realistic?
like one reason since earth has it's own belt & will only move according to it, a random star might just crash into earth since that star can move freely
『But when you think more realistically: humans are stupid, humans make mistakes, lots of mistakes, whether prediction is right or wrong the person who made it will get a bit famous so he/she has plenty of reasons to even make up random lie, there are other reasons, but all things considered, the probability of the prediction being wrong is much higher than it being wrong...』
Add to the fact that not just one, but many scientists claim the same thing, so *some* human minds accept it
then there's religion, which contributes more to it
