Can humans truley be equal?

It's hard to say if humans are really equal. In my mind, nobody is that alike to be considered the same or equal. If the world was all the same, life would be boring and uneventful. Everyone would be the same, and no one would have there own differences. Having differences from other people is what makes you who you are. So why should we change that? Imagine saying the same thing, seeing the same thing, wearing the same thing everyday, not having control over something to make yourself different. Life is supposed to be unpredictable, but why are we wanting to make it predictable?
