I notice that 200ka ago was in the 2nd Quaternary glacial cycle. I hope ya'all can survive in the barren icy coldness without clothing or shelter and only one meal. And of course December is winter for the Northern bits of the planet making it all nice and cosy with the long freezing nights. Maybe those in the Tropics and the Southern parts would fare better?

Yup, I'm the wizard Good guess!

I've run a similar experiment twice before, and this group of humans has made it the furthest. The first time, humanity died out shortly after the Toba supervolcano eruption. Humanity made it to the moon landing the second time, but nuked themselves back to the Stone Age before finding a million digit prime.

The post-1885 stuff may take longer this time. Even if humanity doesn't nuke themselves again before reaching 1990s tech, I wonder how much meaningful information will be passed on. Many experiments would have to be re-run. For example, does any human right now know the Poisson's ratio of Ytterbium without looking it up? The few people in the world who work with that element can find that information without going online, but I doubt that anyone has it memorized. Even if they did, they would probably write down more important information, such as where to find Ytterbium deposits in the first place and what Ytterbium can be used for.

The pre-1600 stuff, on the other hand, is virtually guaranteed. Civilizations all around the world (Europe, the Middle East, South Asia, East Asia, North America, etc.) all got to that point despite very limited contact with each other.

That's right. Without those thinkers, how long would it take for someone to re-discover something such as general relativity? Can this be done within a century or so if all humanity has are vague hints and memories? Only one way to find out!

Freaking boring activity... Can't you raise the wand before writing the notes, so that writing them is part of the magic?

(from which you can see that the wizard, same as the god, is neither almighty, nor very clever either**... for example the god had no idea, when he came into the garden of Eden, neither that the Adam had bitten the apple, nor where the hack he was hiding himself behind the bushes because he was ashamed, etc... or maybe he was losing his powers in the garden, who knows... - we don't want to turn this into a religious fight, and the whole topic discussed here is quite interesting, and we learned a couple of things from it (reading it, and googling stuff related to it)... - for now we still keep our "10 years" for finding the prime, or flying to the moon and back - at the end, what do you need? just a big pipe filled of some sugar and some whiskey, all easy producible from the plenty of the fruits growing around, 200k years ago, hehe).

----------
Edit ** no intention to refer to MooMoo, who we respect, and we generally like his topics. It is just our philosophy that god, and generally any god-like being, if it exists, then it is either stupid or mean, or both. This belief is reinforced daily when we look around us, and when we look in the mirror in the morning. Man is such a bad design...

Hmm, that doesn't seem too bad. It might be good to go over how to do the sieving with no more than rudimentary writing equipment -- maybe something like charcoal or chalk on wood or stone; or perhaps a stick in sand or dust.

I suppose the first thing to do would be to compute Mod(2, p)^74207281 for each p. Then, odd multiples of p greater than 2^74207281 could be sieved out without having to write out any huge numbers.

In that case, where are all the fossilized human corpses?

A few billion immediate deaths would have left quite a sizeable geological signature. The majority of corpses would have been eaten by scavengers but lots should have survived. After all, we're still pulling frozen mammoth out of the tundra and there were surely very many fewer of them then than there are humans now. There should be bones everywhere to be found in what were then bogs, shallow seas, caves, sandy deserts and the like.

Removed as a part of the reset, I assume.

And now imagine all the rapists, murderers, paedophiles, arsonists, etc., that will suddenly become free to roam about.

Ah, but think of all the rulers and politicians who will have to settle for lesser crimes than mass slaughter and all their other current perks.

Sorry for the off-topic, but just because someone asks a question, it doesn't mean they don't already know the answer. Haven't you ever heard of teaching by asking the student questions?

Also, you don't know God's intentions when man was made. Efficiency might not have been his goal. What was your goal the last time you made something with your own two hands?
