Abstract: We propose a background-independent formulation of cosmic inflation. The inflation in this picture corresponds to a dynamical process to generate space and time while the conventional inflation is simply an (exponential) expansion of a preexisting spacetime owing to the vacuum energy carried by an inflaton field. We observe that the cosmic inflation is triggered by the condensate of Planck energy into vacuum responsible for the dynamical emergence of spacetime and must be a single event according to the exclusion principle of noncommutative spacetime caused by the Planck energy condensate in vacuum. The emergent spacetime picture admits a background-independent formulation so that the inflation can be described by a conformal Hamiltonian system characterized by an exponential phase space expansion without introducing any inflaton field as well as an {it ad hoc} inflation potential. This implies that the emergent spacetime may incapacitate all the rationales to introduce the multiverse hypothesis. In Part I we will focus on the physical foundation of cosmic inflation from the emergent spacetime picture to highlight the main idea. Its mathematical exposition will be addressed in Part II with a generalization of the emergent spacetime picture to matrix string theory.
