Proponents of abiogenic theories propose that hydrocarbons on other planets can be explained by the same processes that form hydrocarbons on Earth, which are believed to be abiotic or non-biological. According to this hypothesis, hydrocarbons are formed from deep carbon deposits in the Earth's mantle, possibly dating back to the planet's formation. The presence of methane on other planets, such as Saturn's moon Titan, is cited as evidence supporting the abiogenic theory. Additionally, the formation of hydrocarbons called Tholin through the action of ultraviolet light and solar wind on methane and nitrogen is another example of abiotic processes at work. These proponents argue that the laws of physics and chemistry support the abiogenic origin of hydrocarbons, suggesting that such processes are not exclusive to Earth but could occur throughout the universe.
