The invention of the light bulb helped mankind [in my perspective] because we couldn't use flash lights and fires forever. all you do is hit a switch and there is light that hits in every direction of the area its lighting
It will be like a generator and generate it to light up the light bulb. I hope this helped you and good luck with your answer!
it helped by not having to light a fire.
it helped to heat meat back then and the light from the bulb lasted longer then the lantern light also it was brighter at times
because the bulb is blown !
Well Thomas Edison invented one main thing that changed mankind. He invented the light bulb. The light bulb (obviously) lights up the room if it is dark or makes a light place lighter.
He didn't get electricity, he studied it and also found men who helped Thomas Edison get electricity for his light bulb
