What are the 3 most important discoveries/inventions?
I was wondering if there is a general consensus world wide about which inventions and or discoveries have had the MOST favorable impact on human life from it’s start (I don’t care what you believe as far as evolution -vs- creationism) to the present day. Looking at all aspects, here are my choices, in chronological order. 1. Fire, the ability to make at will and control. I think this opened up countless options for humans, from cooking food to seeing at night, defense against animals, etc. 2. Alphabet/writing. All the knowledge gained by the previous generation would be useless without a way to pass on and preserve long term. Not just English but all writing forms (cuneiform,hieroglyphics,Cryillic) If you are reading this now give thanks to the Phoenicians. 3. Electricity. Honestly, just how f**ked would the entire world be without it, from what you are doing on the computer now to heating your house. I know I left out a lot, but I was going after the most far ranging choices. What do you think?

Where can I learn home canning and food storage?
I’d like to learn how to do home canning, food dehydrating, etc. in order to preserve food for storage.
I know there are a lot of “how to” videos online, but I’d like to find a way to learn in person so that there is less chance of making mistakes given the potential food safety issues.
Any suggestions on where I might be able to learn these skills?
