Jj Wang : I’m like: hey this all sounds pretty good . . . OH GOD NO THE MOSQUITOES NO PLEASE

Lion Lance : You’re an alien: your people have just landed on a new planet inhabited with strange unintelligent life forms and rich plant life! You’ve been issued a new life on this planet, and have decided to explore this strange new alien world. After a while of hiking, climbing, and exploring, you finally find something that sends a chill down your spine. A towering structure, a mass carving of four beings you don’t understand. They’ve been worn, eroded, etc. and you realize, maybe you aren’t alone here.

Rundown Galaxy : While Nokia Phones won't have a scratch 😃😃

Raphael Chen : 0:25 “So what would happen if every human on Earth suddenly disappeared?” Uh, don’t know. The astronauts on the ISS would probably be really confused.

Sharukh Mastan : This made me happy for some reason. We are the bad guys.

thisissparta300ful : What about nuclear meltdowns. Probably would have more of an effect than the oil refineries

Ranielle Libunao : Kinda like reminds me of the I am Legend movie. 🤔

Square Peg : The only thing that will survive forever that humans made is the nokia 3210

Pranil Raja : ...And still, a Nokia 3210 will still be working, thousands of years later.

Tryptamine Odyssey : I can’t wait for future species to find Nokia fossils buried deep in the earth

Xu Bin Ooi : Who else flinched when hearing the mosquitoes. lol

chatsworth777 : This is completely ridiculous. You make NO mention of 238,000 fuel rods that must be cooled by circulating water. Forget for the moment all the thousands of fuel rods in reactors. You completely ignore that Earth's climate is cyclical bringing regular ice ages. Your beliefs about manmade CO2 show ignorance. Look at long term CO2 levels,,, UP and Down. You make no mention of long-term solar cycles. Earth is moving out of an area of dust protection from a big part of the background cosmic rays. The mutation rate will go way up. NASA says that we are currently going into a temperature minimum. Nobody knows just how low the temps will go. There is growing evidence that Sol sends us a micro-nova on a regular basis (Suspicious Observers)

My name is Mr. Meme now : Good question Nothing will happen the earth will continue to live on just like every other species that went extinct

Me:then bomb them with nukes War me:and plan c? Me: USE A GOT DAM TSAR BOMBA! War me: and that fails? Me:*summons creative powers* them I'll delete them.... Scientific me: but then there would be consequences. Me: then I'll make more Mosquitos....but it won't be annoying.(and deadly)

Bernicia Angel Tirta : Infinity war but Thanos accidentally snapped twice

Justice Dodson : The biggest rip off of “Life After People” I’ve ever seen lol

octopisashimi : one human from each different civilization on earth survives, but live upon this "new earth"

Miguel Martinez : This documentary started all wrong if there is darknes caused by artificial clouds then the climate would see a dramatic cooldown possibly starting a mini ice age than it would cause a hole range of diferent outcomes than the ones shown

June A : This really ruin all post apocalyptic movies I’ve watched 🤣
