Could an ancient civilisation create plastics on Saturn's moon - Titan?
Much like how we forged metals and glass here on Earth... To prevent it from being impossible from the start fire can be produced using a special type of plant that can burn in Titan's native atmosphere.
The hydrocarbons are native to Titan so for example Titan has lakes of liquid methane/ethane and has huge sand dunes made of organic material in other words plastic so no need for oil.
My question is could one create useable plastics from it using the sort of technologies that a civilisation which is a sort of hybrid between civilisations like the Ancient Greeks and Aztecs all the way to the Renaissance era. But the wouldn't be able to use metals or glass. Since Titan is mainly made of water ice and organic materials so one would be limited to Native American/Stone Age-like tech.
I only have an A-level knowledge of Chemistry since I decided to study Physics at University but to my understanding most plastic require great temperature which is feasible with fire but without metal - the great pressure that most of these processes require isn't so feasible.
