  This is a chapter of the planned monograph "Out of Nowhere: The Emergence of
Spacetime in Quantum Theories of Gravity", co-authored by Nick Huggett and
Christian W\"uthrich and under contract with Oxford University Press. (More
information at https://beyondspacetime.net/.) This chapter introduces the
problem of emergence of spacetime in quantum gravity. It introduces the main
philosophical challenge to spacetime emergence and sketches our preferred
solution to it.
