Where do they go?

I want to know where all the shooting stars go
where the clouds that float by
the snow that flys around
the rain that drops
and the leaves that fall down
the wind that blows through
the thunder that cracks sound
the lighthenining that strikes bright
the sun that fades dim
the water that runs dry
the mountains that cave in
the smoke that clears out
the fire so fast to burn
the people that leave
they never seem to last or return
