Neanderthal lived in Africa?
Yes, discovered in Germany, but for the most part they lived in Africa.

So they didn't only live in Africa then. That really was my point.
Yes, I mispoke (I edited it immediately, but you beat me
). But the point is they didn't live all over the world. Only homo sapiens spread out that much.

But they were still significantly spread out (considering there were no aeroplanes in those days). It is the significance of this spread that makes one (or at least me) wonder how every one of the pre sapien hominidin died - without exception.

There were, but they weren't fit. Neanderthals existed until some 50,000 years ago, but they had a larger brain that required about 6,000 kcal/day, and during the ice age that was ruling at that time, food was sparse. Archaic H. sapiens had a less calorie dependent brain. If I understand the science right.
Here, should have started with this.

The ice-age lasted for about 1.8 million years. So the neanderthal evolved during the ice-age and then died because of it?
As is my understanding humans basically started in Africa, in the great Rift Valley and migrated everywhere else.
We adapted and survived. Others perished. That's just what happens. If a species goes extinct then they either didn't adapt adeptly to their environment enough to survive. Or something happened to ensure their destruction. Abrupt change in the ecosystem maybe?? Now granted my knowledge of ToE is **** as I am not a Scientist. So ehh.
But really this is like asking why rainbows appear to us in the order of colours they appear to us as. There's an explanation I'm sure, but it's best to go straight to the experts or credible literature on the subject. Asking this in an online forum doesn't really do you good in the long run. Because who knows how many people will have enough experience in the discipline to answer properly.
Also what the hell is an "evolutionist?" Are we to call Physics Professors "gravityists" too?

No. The last ice age started about 100,000 y.a and ended some 12,000 y.a. If I understand it right.

Well, no one seem to have a problem calling some people "Creationists" so I didn't think it would offend anyone to be called an "evolutionist".
If you've read many of the evolution vs creationism threads here you will know there actually are quite a few experts on the subject in this forum.

From what I read this last glacial period was merely part of a greater ice-age that was from at least 1.8million years ago.

Interesting read. Quite a lot of theories. In the end the main theory appears to be about competing. And that is what I don't understand. Why do we make the assumption that we would be competing with other hominins? I expect that as some threat came along the other hominins would simply have moved away from humans. Certainly the earth is such a large place that I find it hard to believe that the number of homo sapiens in existence 30 000 years ago was enough to deny the neanderthal and other hominins all options of survival.
It think this doubt is expressed in the last part of the link you shared:
But there is one other possibility, which we can't entirely ignore. Maybe it was pure chance. Maybe our species got lucky and survived, while the Neanderthals drew the short straw.
If the idea that other hominins were simply out competed was as strong as some might suggest, there would be no reason to consider that humans were "just lucky".
I think you may be looking for an overly simple answer when the truth may be it is a combination of several factors. I don't think simple competition is the answer, but that does not mean it didn't play a role. Nor do I think it was simply a matter of chance, although that too may have played a role. Competition, climate change, luck, whatever. But the fact remains species go extinct.

The last Glacial Maximum was about 20-30,000 years ago.
Besides, there's also the fact that H.s developed more advanced hunting techniques and tools.
Yes, it does. Thanks.
Good question!
I'm not sure how a scientist working in the field would answer this, but my guess is that environmental and climate change, followed by disease and parasites, killed them off. A recent theory on the extinction of Neanderthals, for instance, blames climate and environmental change.
I try to keep in mind that 99% of all species the earth has seen are extinct. There's a good chance of anything going extinct, not just our ancestors. For instance, how many species of saber tooth cat do you see around today? I'd guess there were at least twenty species in the past. Again, how many species of elephant like animals are alive today? Two, if I recall, and both proper elephants. But in the past, there were at least three or four in North America alone. For the ancestors of things living today to have gone extinct is not unusual at all. In fact, it seems to be typical.
By the way, unless you call people who accept the theory of gravity "Gravitationalists", you might want to reconsider calling people who accept the theory of evolution, "Evolutionists". The use of that term makes a person look like they are attempting to make a point in a childish and immature manner.
Two words: Different habitats.
There are around 25 different habitats in Africa. Humans are adapted to nearly everyone of them with the notable exception of the rain forest. The rain forests of Africa are largely inhospitable to humans, and the main problem is, there's not enough for humans to eat (That's a main reason just about the only group of humans that has managed to at least partly adapt to African rain forests -- the pygmies -- are of small stature). Even the pygmies are only partly adapted to the rain forests and could not actually survive without the help they get from trade with people living outside the forests.
On the other hand, chimps, bonobo, and gorillas are very well adapted to the rain forests. Consequently, it has only been in recent years that we have invaded their turf, so to speak, and nearly driven them extinct in the wild.

They died. Either because they couldn't adapt (in some cases) or because we killed them (in others).
