On this Earth, every creature or living being
live for a very short time. Living things do
not live for ever. They die after completing
their lifespam. For life to go on, living things
must produce more of their own kind.
Hence, we can say new living beings
resembling the parents are produced.

its parents? Have you seen cute little chicks
following the mother hen?
