Logic help

Between position A and position B, there are an infinity of points. If An object spans from position A to position B, it resides in an infinity of points as well. Though if the object is located in Paris France, it is not in London England at the same time. How can this be possible if the object covers an infinity of points?

It’s not for school or anything, i’m just bored, and i’m sure it’s a dumb question, anybody care to clear it up.
