The premature acceptance of the standard cosmological model, the 'LambdaCDM' paradigm, is questioned; Self Creation Cosmology is offered as an alternative and shown to be as equally concordant with observed cosmological constraints and local observations including the EEP. The Brans Dicke theory is modified to enable the creation of matter and energy out of the self contained gravitational and scalar fields constrained by the local conservation of energy so that rest masses vary whereas the observed Newtonian Gravitation 'constant' does not. There is a conformal equivalence between self-creation and General Relativity in vacuo, which results in the predictions of the two theories being equal in the standard tests. In self-creation test particles in vacuo follow the geodesics of General Relativity. Nevertheless there are three types of experiment, including the LIGO apparatus & Gravity Probe B geodetic precession, which are able to distinguish between the two theories. Self-creation is as consistent with cosmological constraints as the standard paradigm, without the addition of the undiscovered physics of Inflation, dark non-baryonic matter, or dark energy. It does demand an exotic equation of state, which requires a false vacuum energy determined by the field equations. The two conformal frames conserve energy or energy-momentum and choose photons or atoms as the standard of measurement respectively. In the former frame the universe is stationary and eternal with exponentially shrinking rulers and accelerating atomic clocks, and in the latter frame the universe is freely coasting, expanding linearly from a Big Bang with rigid rulers and regular atomic clocks. A novel representation of space-time geometry is suggested. (Abridged)
