Answer:
What has 4 fingers and a thumb but isn't alive?
I shoot but never kills
What has keys but no locks a space but no room and you can enter but can't go in?
I walk on 4 legs in the morning, 2 legs at noon, and 3 legs at night. What am I?
Sometimes I fly as fast as the speed of light. Sometime I crawl as slow as a snail. Unknown until I am measured but you will certainly miss me when Iām gone.
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
