I conjecture that a flat 10D compact universe emerged out of nothing (By ``nothing'' I mean no notion of space and time) with all it's symmetries intact: Poincare invariance, conformal invariance and supersymmetry, it's massless moduli fields, and a zero energy density. Its subsequent evolution and spontaneous breaking of these symmetries or by quantum fluctuations leads to topological defects on this superspace which are the fields we observe (or haven't yet observed) propagating in this spacetime. By the law of naturalness it will restore all these broken symmetries. In recent years, the cosmological constant problem has metamorphosed to a new problem of finding a selection mechanism that selects our vacuum out of a string theory landscape or resign to anthropic reasoning. I provide a new perspective for solving this problem using a multistep approach based on the wavefunction, inflation and conformal symmetry.
