Believe in God?

would i say something really terrible if i said i didn’t belive in god? would it be that terrible that i would certainly be excecuted by some christian? hopefully not. just a few statements why i don’t really believe that god exists.
1. if god really would exist, and he/she/it would really be that great and loving, how COULD he/she/it let things like libyen happen? i don’t understand this.
2. if god really would exist, how does he show it to us? like that non-appearing in our sight, what signs us that he/she/it is really here?
3. if god created the world, why is that thing called EVOLUTION? were adam and eva first there, and gone and THEN were all the dinosaurs and things? me thinks not.
