Earth and meteorites, volcanoes then sea,
Single-celled life then came to be.
Animals with shells, then fish in the sea,
Land plants, amphibians came next, you see.
Reptiles, dinosaurs, mammals came along,
Birds flew in the sky with their new song.
Plants with flowers, then grasses were next to be
Then us, humans, you and me.
