Why these children are in the school at 07:00 ! [If it's a question: "Why are these children at school at 07:00?/Why do these children get to school at 07:00?". If it's an exclamation: "Why, these children are at school at 07:00!/Why, these children get to school at 07:00!]"

I wake up at 06:45 every workday. Then I cook 4 eggs. One day, wWhile I was eating breakfast, I looked out of the window. I saw children (gereksiz: who were) walking to school, but it was only 7 a.m. and clock is only 07:00 . This system is very bad. [OK, but imprecise. Belki: "Going to school so early is bad for children".]
