Slow is a relative term. If you move at 1 mile a year, you can be round the world in 25 000, which is a bit of a blink in geological terms.
Also, don't forget it was not a migration in the sense that birds migrate FROM somewhere TO somewhere. These early humans didn't wake up one day and fancy a holiday by the Mediterranean. They were following food supplies, or looking for new sources.
One theory is that they moved along coasts. They would set up a camp, and exhaust all the readily available food, which would be sessile life like shellfish and anemones, and the inshore fish such as wrasse. Once that was gone, they would move to an area which hadn't been exhausted, which might only be 3 or 4 miles away.

Because it's such a long distance. And human life expectancy was so much lower then. We are not a migratory species. Look at people like the Bedoun in Africa, they don't move very far, they mostly stay nearby where they are. They only move if they have to.

Frankly it wasn't that slow at all. Remember that there is little reason to migrate if things are going well. Having said that the main pressures to move largely came from population growth. As tribal societies grew too large and unwieldy, they spread out. In fact we took over this planet pretty bloody quickly.

it just appears slow because of the numbers game (there were far less people back then to colonize new places) and the fact that people didn't have faster transportation than horses or feet

It never happened. Thats why its so slow.
I had to learn this in History class, darn it. Because they were not intellegent enough and couldn't talk. So they couldn't communicate. So they couldn't be like "Dude, theres a bear behind you" or nothing. Also, they were nomads right? So they followed the animals. When the animals left Africa they did.
But don't worry, its all crap.

Um, because it was a long walk?
