If you have ever been thoroughly befuddled by Zeno’s paradox on the impossibility of motion, then you might find William Lane Craig’s response below very helpful. This is also discussed in this book “Reasonable Faith” 3rd edition.
Ostler indicts this argument as “a slight-of-hand trick like Zeno’s paradoxes, for even though a baseball must pass through an infinite number of halfway points to reach the catcher’s mitt, somehow the baseball actually makes it to the mitt.”155 He thereby fails to note two crucial disanalogies of an infinite past to Zeno’s paradoxes: whereas in Zeno’s thought experiments the intervals traversed are potential and unequal, in the case of an infinite past the intervals are actual and equal. Ostler’s claim that the baseball must pass through an infinite number of halfway points to the mitt is question-begging, for it already assumes that the whole interval is a composition of an infinite number of points, whereas Zeno’s opponents, like Aristotle, take the line as a whole to be conceptually prior to any divisions which we might make in it. Moreover, Zeno’s intervals, being unequal, sum to a merely finite distance, whereas the intervals in an infinite past sum to an infinite distance. Thus, it remains mysterious how we could have traversed an infinite number of equal, actual intervals to arrive at our present location.
