In particular, we consider the varying speed of light (VSL) theory and varying gravitational constant theory (VG) using the specific ans\u00c3\u00a4tze for the variability of constants: c(a)\u00c2 =\u00c2 c0\u00c2 an and G(a)=G0\u00c2 aq. We find that most of the varying c and G minisuperspace potentials are of the tunneling type which allows to use WKB approximation of quantum mechanics. Using this method we show that the probability of tunneling of the universe ``from nothing'' (a=0) to a Friedmann geometry with the scale factor at is large for growing c models and is strongly suppressed for diminishing c models. As for G varying, the probability of tunneling is large for G diminishing, while it is small for G increasing. In general, both varying c and G change the probability of tunneling in comparison to the standard matter content (cosmological term, dust, radiation) universe models."
