I can fly but have no wings. I can cry but I have no eyes. Wherever I go, darkness follows me. What am I?

Clouds!

Did You Know?

Clouds "fly" across the sky, "cry" rain, and cast shadows (darkness) wherever they move! A single cumulonimbus cloud can weigh over one million pounds—the equivalent of about 100 elephants floating in the sky. The water droplets are so small and spread out that air currents easily keep them aloft.
