So if early man accidentally found out that rubbing things together create heat which then results in fire, that is an invention too?
The fact that rubbing things together to create heat which then results in fire is a discovery. Things used to create heat which then results in fire are inventions.
Things like matches and lighters are inventions. But for primitive people, making fire (if they even up to making it rather then just keeping it) usually consists of creating heat/spark from friction and applying it to natural fuel. None of the two - friction or natural fuel - can be said to be an invention.
however you could argue that using the principal of friction coupled with the concept of tinder is an invention
We have a tendency to grossly underestimate early man by calling him primitive. Many recent discoveries are showing us that they were more advanced and had the same brain power we do. Just remember primitive man could survive without electricity. If we lost power most of us idiots wouldn't know how to survive or start a fire on our own. Hell we couldn't plant a crop, fish, or hunt any animal either without modern conveniences that depend on electricity to manufacture.
If they were inspired to use tinder from some intuitive light-bulb moment. But most likely we started using tinder when we saw that they catch fire easily. It was more an observation (discovery) than any new concept we invented - like say x-ray.
Physicist Johann Hittorf observed tubes with energy rays extending from a negative electrode. William Crookes investigated the effects of energy discharges on rare gases. Heinrich Hertz began experimenting and demonstrated that cathode rays could penetrate very thin metal foil (such as aluminium). In 1887, Nikola Tesla began to investigate X-rays and produced the bremsstrahlung process. In 1895, Wilhelm Röntgen began observing and further documenting X-rays while experimenting with vacuum tubes.
x-ray was discovered by observation
from wiki:
it started with the Hittorf bloke observing what happened with electodes, and went from there.
most inventions are made by observing a phenomena and investigating further
Some of you know where this is from. I'm just wondering what the general opinion out there is.
Naturally created fire (lightning strike, sunlight focused through sap, volcanic eruptions etc) was discovered. Human-created fire was invented.
I would suspect we were using the fire we discovered - and inventing new ways to keep it burning longer - for a long time before we invented a way to make it ourselves.

I'll bite.
So, where is this from?
Either of those are potentials, probably the first rather than the second.How? Did early man discover friction and were applying it to something else, and then one day a thought occur: why rubbing stones together cause them to be hotter, if I put some dry brush to them it might catches fire, let's try and see. Or did they come across it accidentally?
