N2 - We consider the possibility that the vacuum energy density of the MSSM (Minimal Supersymmetric Standard Model) flat direction condensate involving the Higgses H1 and H2 is responsible for inflation. We also discuss how the finely tuned Higgs potential at high vacuum expectation values can realize cosmologically flat direction along which it can generate the observed density perturbations, and after the end of inflation - the coherent oscillations of the Higgses reheat the universe with all the observed degrees of freedom, without causing any problem for the electroweak phase transition.
