Your question is good. You’re missing understanding of time dilation and frame of reference. An explanation of the theory of relativity is at least pages long.
The first book I ever read on the subject, and IMO the best introductory text for any non-physiscist, is Stephen Hawking’s “A Brief History of Time”. But, any introduction to relativity should answer your question.
