What would this world be like without me

Feifei asked her mother:
"When there was no me in this world,
Is it... deserted and empty? "

Mom smiled and said, "No way!
The world was very lively at that time. There was a father and a mother!
Even earlier, there were grandparents, great-grandfathers and great-grandmothers!
Earlier, earlier, there was your wife...
Anyway, I can’t count how many great-grandfathers and great-grandmothers there are.
They lived in caves and invented painting. "

"Then, earlier, earlier, earlier,
What about when you were a kid when the world was still very, very, very, very small...? "
