If we're including fiction then whoever pressed the button on the Death Star to blow up Alderran...

Or probably just like some random dude from Warhammer 40k

It's always funny to hear Christians say God is perfect and never makes mistakes then say God had to start over because the time before Noah was a mistake.

In 10000bc the world population is estimated to be between 1-10 million people

Depending on the year you could kill everyone on earth and it wouldn’t even be close to the Holocaust

Dude would totally be a psychopath if he was real.

He did bring some family. Who, by extension, repopulated the world. Like when the sons of Adam and Eve got married.

Mosquitos: "Pathetic."

This is kind of more complicated than you'd think. Mostly because after the industrial revolution the population of the world exploded and there are far more people now than there used to be. For example, the world population today is ~8 billion, while in 1930 it was only around 2 billion. If you go back to the ancient world, the population was only about 300 million people in 1 AD. Now of course trying to estimate a theoretical antediluvian population is kind of impossible since the Bible doesn't contain any census data until the next book, but if we take the date usually given by Creationists of ~2000 BC then the population would have been between 20 and 70 million. So still higher than Hitler* but not by as much as you might think.

*This is if you only attribute Holocaust deaths to Hitler. Hitler killed many more people than just the victims of the Holocaust and you could make the argument that most of the people who died in the European theater in died as a result of Hitler, and by that metric Noah actually loses to Hitler here.

I just realized I don't really know about Noah's story. So did all of humanity drown? How'd he repopulate it?

Yeah uhm from real people.

If you're still a Christian in your adulthood you've either not read the Bible, you're dumb as shit, or you're just afraid of your family judging you.

Where's the ghengis Kahn reference?

The vast majority of "Stalin's" deaths were from Lysenkoism rarher than Stalin directly.

https://en.wikipedia.org/wiki/Trofim_Lysenko#Consequences_of_Lysenko's_views

Lysenko forced farmers to plant seeds very close together since, according to his "law of the life of species", plants from the same "class" never compete with one another.[9] Lysenko played an active role in the famines that killed millions of Soviet people and his practices prolonged and exacerbated the food shortages.[9] The People's Republic of China under Mao Zedong adopted his methods starting in 1958, with calamitous results, contributing to the Great Chinese Famine of 1959 to 1962, in which some 15–55 million people died.[note 1][9]

Even the Gulag system only killed 1 million of the 18 million people who passed through it. Most survived internment.

Who to say Noah wasn't from an advanced civilization. Do you think America and half the west would survive a 40 day flood. We can't survive a 2 day flood.

That's our procedure during a school lock down as well. Lock the door and hide in silence. No one gets in or out. If someone is stuck in the hallway, we cannot open the door for anyone. That's the procedure.

Hitler or Stalin didn't kill those people personally, they just commanded others to kill them. Probably some suicide bomber killed the most people directly.
