We explore the possibility that the expansion of the universe canbe driven by a condensate of spinors which are free ofinteractions in a 5D relativistic vacuum defined in an extended deSitter spacetime which is Riemann flat. The extra coordinate isconsidered as noncompact. After making a static foliation on theextra coordinate, we obtain an effective 4D (inflationary) deSitter expansion which describes an inflationary universe. Wefound that the condensate of spinors studied here could be aninteresting candidate to explain the presence of dark energy inthe early universe. The dark energy density which we are talking about ispoured into smaller subhorizon scales with the evolution of the inflationary expansion
