the first fire was supposed to burn for eternity but one day a demigod who was banished to live on earth found it.the demigod knew that gods could make incredible things but never had he seen something so magnificent.it was like a mini sun but the creation of plastic caused the fire to explode and turn into ashes which spread around the earth.
the demigod was caught on fire which eventually caused him to burn to the bone.
after he was burnt he was still alive but only a skeleton.
after this the skeleton made a deal with hades.he could go back to godworld but he had to to harm the earth.fire could hurt demigods but didn't spread on anything except demigods and regular gods.But he was half god so he could shape fire but with great difficulty.he used a metal axe to chop some firewood but when he put the wood in the fire and started making fire able to spread on more things he dropped his axe.
the creation of plastic
when he dropped the axe hen thought he dropped it in the grass but part of the metal was in the fire.when he finished the ritual the final step was to melt hi bones in the fire which melted with the metal and created plastic.
