By asking me this question, you're asking me to take up an antithetical perspective for the sake of responding to you. At the end of my comment, you will still argument. If you genuinely want to know the position, here it is;
We are, simply put, organisms that have compounded in different environments.
We all have very similar physical functions. Much more akin to each other than other species.
If, for instance, an alien organism came to attack earth, we would not be looking at race, we would not be focused on and perceiving through the lens of race.
What is distinguished as race, at some point, has to be made up based on someones created projection of what signifies these categorical differences. These categorizations are human projection.
Theres been a number of instances where I have personally found more in common with someone whom is categorized as another race, than some people whom are categorized as my own race.
People think in terms of race because there has been similar conditioning.
Similar conditioning can mean a similar shared identity, but people really do a disservice to both the individual and the individuals environmental conditioning here.
That's why people look to race. Similarities.
By virtue of even believing in such a thing, one takes on what gets culturally established as "race identity".
To answer your question directly, people can "tell races apart" because there's been projections of categorization.
I can tell there's differences between me and other people "of my race" just the same. I can do this all the way down to my individuality.
If people perceive in race, then race is real.
Doing so is horribly constricting to ones identity and breadth of development, though.
