The human race was extinct, and had been it for hundreds of years. However you were a human, let me explain

Your “dad” was a robot and a bit of a scientist, you lived in a space ship. He had gone to earth and somehow found human DNA

He had used the DNA to form an artificial womb and created you. His daughter that he loved so much.

He had obviously had challenges raising a human child - especially a baby. It took time for him to find out what to feed you, how to comfort you and such.
