Can we survive without the sun?

We take it for granted that the sun is just going to keep on shining… But what if it didn't? Could we survive on planet Earth without the rays of the sun beating??

No.
We need sunlight for growth.

Long term? no

we need sunlight for crops

We can actually survive without the sun.but we wouldn't be healthy..
Our bodies need to sustain a fair amount of viatims from the sun..
Artificial light is not the same.
We can see this effect on plants which are grown via indoors compared to outdoors.
