If you read the text, it says that the ark came to rest on the hills/mountains of Ararat, which is northwest of Mesopotamia, away from the Himalayas, which are far to the east. (Ararat is roughly as far from the Himalayas as Perth from Canberra.) Mesopotamia is very flat and low-lying, but to the northwest, north, and northeast you reach uplands and eventually mountains before getting back down to the Black Sea.
Humanity originating in Africa versus Noah landing in the region of Ararat is not a conflict with the Bible. Humanity does not originate with Noah. Of course, how the physical process of creation of our bodies (which paleontology tells us about) relates to becoming spiritually fully human (which Genesis 1-3 tells us about) is highly speculative. The arbitrary way that different young-earth advocates claim that various fossils are or aren’t human reflects the reality that we don’t know just what physical features and preservable behaviors are the key indicators of being in God’s image. There are multiple models that take the biblical account seriously. Claiming that this is “the bible model and the secular one” is a serious misrepresentation. Indeed, the modern young-earth model is not very biblical in its selective modernistic exegesis and double-standards.
Do not forget to consider how Ararat could be there at all in a young-earth model. By the 1770’s, it was clear that large volcanoes required more than a few thousand years to build up, plus all the time involved in forming the rocks underneath them; indeed, the Roman Catholic authorities banned the claims of one young-earth advocate in the late 1700’s after investigating the question. Each lava flow or ash eruption has to have time to form and harden (and the ash has to be concentrated in a particular spot, which can’t happen during a modern young-earth global flood). That layer has time to weather, often all the way to forming soil, before the next eruption comes along. How many individual layers make up a large volcano like Ararat? In turn, the rocks underneath are made of numerous layers as well, each one taking some time to form and the vast majority clearly not deposited during a global flood. No flood geology model deals honestly with this evidence. A truly biblical model will seek to correct and improve itself, rather than resting on the inerrancy of the interpreter.
