If every astronomer were a theist, what would happen?

I'm uming that the old Geocentric idea would still hold, since pre-modern astronomy church doctrine maintained that the Earth was at the center of creation. That would mean no interplanetary probes for starters. Fortunately, most theists now accept the heliocentric theory (e.g., our Earth orbits the Sun) just as they accept the Theory of Gravitation. Now if we could just get them to accept the Theory of Evolution . . .
