Answer 1

$\bf\large\color{Red}{Hey \: Friend}$

Thomas A. Edison invented bulb with a lot of failures in his experiment.
He also concluded his Positivity by saying that "I have not failed l, I've just found 10,000 ways that won't work."

Now your Question, What would be the life of people without invention of BULB ??

Let us start,
Light is there on Earth at day time because of Sun.....Obviously everyone knows that...

But at night time what would happen if no Light is there...Our life would be totally stopped due to the presence of No Light.....Can you Imagine??

Only there would be a slight light coming from Moon and now think of a time when there is no moon due to some Weather Problems.
The life of people would be totally stopped, none could even see due to darkness.

CONCLUSION:--

Invention of Bulb is a very huge or the greatest invention to Mankind......
