In all honesty, we could survive after the sun went out, but not for long.

As in less than a few months. The sun provides an enormous amount of solar energy to the planet in the form of heat and UV. Without the sun, global temperature would plummet FAST. Plants freeze to death, hydrologic cycles will freeze in their tracks, and stepping outdoors without layers upon layers of clothing would be an act of suicide. Just think of The Day after Tomorrow, except it would only get colder and be permanent.

It would be a lot less than a few months. There would be many factors that would kill us if we didn't have the sun.

Not to mention that, without the sun, our atmosphere would become liquid and eventually solid.

We need its light. We need its heat. We need its energy.

Without the sun - without a doubt - there?d be no you and me.

Assuming the sun was to just "go out" and not die in normal fashion, in which case the Earth would be roasted by a rapidly expanding sun before we even have to worry about being cold, and also assuming humans could survive, the earth would eventually cool to about 2.7 Kelvin (or about 270 degrees below zero). Being just a few degrees above absolute zero nothing would survive. The entire plant would freeze to the core. Our atmosphere would be gone. We would be unprotected from high amounts of solar radiation that would assail our plant. Of course oxygen would be a thing of the past. So while we can create "artificial sunlight" quite easily life would end without the real thing.
But if you insist it would be great without the sun just take a trip to northern Siberia during a six month night and let us know how it goes.

yeah, our planet would be pelted a lot without the sun.
