Saturn's moon Enceladus has eruptions at 15.8 gigawatts which is considered by science to be impossible for a planet that size to continue for billions of years. (Apparently the geysers of Enceladus actually impact the field rotation of the much larger Saturn)
The rings of Saturn have ice that appear relativley "clean" despite supposed "billions of years" of impacts with dirty micrometerite contamination.
The half black and half white Saturian moon Idpetus has carbon dioxide ice that hops from pole to pole. About 12% is lost in space each year. If the solar system was 4.5 billion years old---there would be none of this left to hop from pole to pole on Idpetus!!!
The most famous moon of Saturn, Titan, has methane in its atmosphere. As the solar wind erodes the methane it turns it into a haze then back into methane. It should take about 10 million years, at the current pace, for it to "freeze out" the nitrogen in the atmosphere as a result of this process. So it can't be anywhere near "billions" of years of age.
Also, the raining down of methane over billions of years should have produced an ocean of methane on the surface of Titan. But when the Huygens probe landed in 2005, it was with a thud in mud...not a splash in an ocean of methane.
These are the generations of the heavens and of the earth when they were created, in the day that the LORD God made the earth and the heavens, Genesis 2:4
