If Saturn was emitting enough light to sustain life on Earth then it would be very hot , and Saturn could not have cooled down to it's current temperature in a few thousand years. It would take millions of years. You cannot change these basic laws of physics. So the whole idea is a non starter. Next subject please!

I said on this forum, that I think that Saturn did not came as an "intruder" into the Solar system, but that Saturn - just like all the other giant planets of the Solar system - was "birthed" by our Sun.
That what I said was ignored, even though it is more logical to assume that Saturn was created, in the vicinity of it's current position(orbit), than to assume that it was created "somewhere far away", like Cardona and others who follow Cardona think.

If I am right, then maybe Saturn was in the past closer to the Sun, was even maybe at a distance from the Sun that is equal to today's Sun-Earth distance, or even closer.
In another words, I do believe that the Earth was a satellite of Saturn, but the energy that was responsible for the life on Earth, didn't come directly from Saturn, but had as it's source the Sun.
However, I also think that Saturn "transformed" the photons from the Sun into lower energy photons, because without that transform, the photon radiation would have been too harmful for life on Earth. 

Something similar to this "Saturn function" we see with our Moon.
Namely the reason why the round Sun that we see is optically equivalent with the Moon, is because the Moon recycles on average HALF OF ALL CHARGE(photons) that come from the Sun.
And only after the Moon recycling process is completed, are the photons "sent" to the Earth(at the New Moon phase, but as you go closer to the Full Moon phase, photon recycling decreases until it reaches zero).
