If the Earth was destroyed ....

If the Earth was destroyed (as we know it), how long would it take for mankind to return to its current stature?

With us having 'knowledge' of the current - would that mean we would be able to 'bypass' going through medieval times and pre. etc

Or would destruction of our 'mad-made' environment, cause us to revert to caveman status, requiring a full evolution?

We should have established off-world colonies by now. Then it would not matter. We could await the return of Earth ot a habitable state and then return.

All your eggs in one basket springs to mind.
 
Hold on.. is the Earth being destroyed as not?.. a lot of you seem to have overlooked finding a new earth like planet to even start living on..

Or are we talking mediocre Earth destruction? More akin to infrastructure destruction rather than Earth destruction.

I think we need to differentiate between Earth and Human civilisation/infrastructure destruction before i can comment.
 
Assuming all infrastructure was destroyed - unless it was completely vapourised we would still have lots of items that could be used to make things.

To survive you need a clean water supply, shelter & warmth and finally food. Once you have a steady supply of each of these then you can survive. The bigger question is would you want to?
 
Things would end up madmax style, everyman to himself, trying to find enough resources to run the things that survived. With some scrap yard challenge style improvisation. Unless the icecaps melt, then only people on high ground would survive. Id imagine that to stay very much the same just smaller, maybe knock us back 100yrs.

If you were to reset and drop say 100k people into 1000bc, id say some more like the iron age would come about pretty quickly, but better as people would understand the risks of food, germs. The need for sewers and clean water etc.

You tried hunting before? With stone tools?

What about fishing? Sounds quite simple right... but first you need a line and some kind of a hook.

I have indeed and know how to gut, skin and butcher several animals. (and I know how to without resorting to google or SAS survival guides!)

Again you don't need a line and a hook - you are much better building a trap for the fish to swim into. Again it takes time and practice but is a much better way of catching fish.

Ultimately a lot of your food will come from gathering wild fruits and plants that are edible.
 
I imagine that we would "see it coming" gather all the important people together and fire them off into space to watch the firework display. Once it had all subsided to a level we could come back and land again then a plan of action to rebuild "life as we know it would start. re-planting of seeds for harvestable crops, growing of trees until shelters could be made.
It would be along old slog, but as long as we kept the knowledge of today I think we'd be back up and running quicker than we originally did!
Would be nice to start again, without all the scum and the screwed up people in the world!

In the west and the rest of the "civilized" world we would be stuffed but if we were to regress to a more primitive time without technology then I am sure there are some tribes in Africa and south America who would not have any issues.

In our modern society we have become too reliant on other people fulfilling our every basic need
 
Personally i think i could write a general school textbook that would be up to a gcse level in most areas. Im sure some teachers would survive. I have enough random general knowledge to do a fair amount of scientific things too.
Ive studied good old Ray Mears just for this reason alone :)

Easy enough with a nice sharp knife, personally i think i would get very frustrated doing this job with a piece of flint. :o

Absolutely but then frustration pales when compared to survival.

But again you are assuming that not a single iota of any pre fabricated metal will remain - no situation would ever exist to cause that. Plus once you have your first kill you can quickly move to making bone tools which can be nice and sharp.
 
Well, when you see a Tyrannosaurus rex walking down your road, that will give you a pretty good indication of how long it takes a species to re-develop after a cataclysmic event.

The threads kinda gone in 2 directions, are humans wiped out completly and develope from scratch or are we talking a few survivors.

If it were a few survivors Id like to think that we'd be able to rebuild reasonably quickly. Maybe not to what we have now but a standard of living which is acceptable. For example I imagine most people could start a fire and know that boiling water will kill a lot of bacteria.
Although no one may be an expert in a subject such as mining and forging its possible that they may know the basics which is a good start and also, perhaps the fact that knowing its possible would be good motivation.
 
To get back to our basic infrastructure (e.g. buildings, government, etc) I would say about 5 or 6 generations.
 
assuming humanity to some degree survives and can survive in this new env then some basics would return pretty quickly, basic housing, fire, and by extension clean water

if reasonable levels of people were around re-development of some modern infrastructure is potentially feasable within a few hundred years, time of development would vary massively on the number of humans who surivived and the knowledge they have
