It's impossible to say definitively which land was the first inhabited by humans, as there's still much debate and ongoing research in archaeology and paleoanthropology.

However, Africa is generally considered the cradle of humanity based on the evidence we have. The oldest known hominid fossils have been found in Africa, dating back millions of years.

While there are theories about early human migrations to other continents, the most widely accepted theory is that modern humans (Homo sapiens) originated in Africa and then migrated to other parts of the world, starting around 60,000 years ago.

It's important to remember that:

* Our understanding of human origins is constantly evolving as new discoveries are made.

* The term "first land" can be ambiguous as humans likely lived in different areas of Africa at different times.

* There's evidence of early human presence in other parts of the world, but the evidence is generally less conclusive than in Africa.

So, while we can't say for certain which specific land was the first inhabited, Africa holds the strongest claim based on current scientific understanding.
