What arguments are there for human history before civilization occurred

Well civilization started in the Neolithic age. (the new age). Civilization didn't really grow well in the Paleolithic. (the old age)

Some people argue about how the first humans, austrosapiens (I think that's how its spelled), migrated. There is physical proof that the first humans migrated from Africa but everyone argues about how they migrated. Were the world continents together? Or did they find some other way?

Most people don't believe that the continents were together at one time.
