I want to know on a scale how scared you would be if Earth was going to be destroyed by a meteor. Please explain

Zero. I wouldn't be scared. I'd contact as many friends and family members as I could to tell them I love them and to say goodbye.

If the earth would be destroyed, what's to worry? A bigger worry would be if only 1/2 would be destroyed.

Depends on how long between the time you find out it's coming and the time it is going to hit.
