this copypasta you're regurgitating is nothing but ahistorical bs. the racial caste system was invented by European colonizers to divide the world into humans and non-humans(their colonial subjects such as enslaved Africans).

human is a social construct and is classified as a species. race is also a social construct but based on perceived phenotype rather than biology and since not all humans are grouped into the same phenotype under our white supremacist world order, it's ignorant to claim we're all the same race. it's also an inherently anti-Black statement to make because it gaslights Black people's lived realities of experiencing racism every single day precisely because they're not white aka not part of your fantasy universal human race.

asserting that we all belong to the same race would only make sense if you believed that all humans are white.
