Random saying

Okay so there are several things i just don't understand about Mortals.
1) Why do they think blue=rasberry?
2) Why do some of them instist on killing us even though if they do the world will implode
3) Grammar, what's up with it?
4) Spelling, don't get that either
and finally 5) Sayings. Yep. Like 'raised to the ground' WTF? seriously does that sentence even make sense? How can you raise something up and then it's on the ground. And the ground is like down. So it really should be 'raised to the ceiling' or 'brought to the ground'

Just saying.
