Fun fact: The ecosystems of the Amazon Basin rely on around 27.7 million tons of Saharan Dust each year to replace the phosphorus that is washed away by the rains. Without this constant input the local soils would have been stripped of needed nutrients and would be unable to support the plants that currently thrive there.
It looks like the Amazon region was experiencing less rainfall at the time with a corresponding shift towards drought tolerant species with parts of the region as savannahs !!
would be greener on the continents with ice reaching further down because without africa there would be no humans and with no humans there would be no greenhouse emissions and global temperatures would be notably cooler.
Im cutious how much lower the ocean's water level would be t fill in for the missing land because thats a lot of cubic volume and what impact that might have on further revealing existing land due to the lower water levels
It would be far different if the land mass of Africa had never existed. The whole tectonic movement would have resulted in different arrangements several supercontinents ago, with their own effects on climate and life itself.
But if Africa just blipped off one day, maybe. Then you have to explore what a sudden loss of land would do to the ocean waters rushing in, the change in Earth rotation due to its mass being shifted, lots of other things.

Also true for the Indian Monsoon.

The Amazon rainforest survived the African Humid Period though, so what's up with that?

With a different rainfall profile the nutrient loss would have been vastly reduced.

You are looking at the wrong continent to disappear for the effect to be noticeable

I think the point was that humans come from Africa (as in, as a species).

Sea level would be considerably lower, as it would suddenly have a big ass Africa-sized hole to fill.

Unless the land didn't simply disappear but redistributed, raising the ocean floor throughout the Atlantic.
