What do you consider to be man's greatest invention? (Only one invention per answer)
To me....the internet. Without it I could not remain independent.
(says Marisa when it is 105 F / 41 C outside in the shade).
I'd say electricity, without it most of our current day things would not be here. No air conditioner, no computer....
And without a computer, there would be no need for an internet.
No fire no silicon to make any electronics
No fire, no tools from iron or any other metals, including knives
No fire, no pizza. I rest my case!
I would have to say it is the computer. Without them, we would have never gotten to the moon, figured out how to drill for our oil and gas, make knives and everything else better in our lives.
