There is a difference between accepting as real something we cannot see, but can verify its effects, and something we cannot see, cannot verify its effects, and don't need to explain the universe.
Neutrinos were proposed to exist to account for apparent violations of conservation of energy and momentum in nuclear reactions. They were later discovered.
Quantum Mechanics and Relativity developed to account for non-Newtonian effects in atomic reactions and other phenomena. They have been verified in numerous experiments.
Dark Matter was proposed to account for stars and galaxies apparently moving with more than escape velocity, but not escaping. Such matter has not yet been discovered, but some of the effects are observed.
On the other hand, God and other mythical beings have been proposed to account for many features of our universe for which an obvious answer was not available.

As science adequately explains the universe, the tendency to propose mythical or supernatural forces or persons should decrease. God is just the most sophisticated of the various mythical beings mankind has come up with to explain the complicated world he lives in.
There is good evidence of dark matter. What good evidence is there of God?
