It was the creation of fire by those filthy footed cavemen that changed the course of humankind. It’s critical to how we live, even now, 300,000 years later.
Fire creates the opportunity to cook food, heat your surroundings and burn evidence.
I can now say I’m able to do all three of those things in my kitchen. For 15 years I’ve only been able to make a meal and torch the odd incriminating exterminator bill. (Nobody needs to know the extent of my centipede problem.)
NOW … I have heat.
