What would happened if…

What if people had phones at that time? Clearly, many events would not have happened in history. For example, let’s say Marathon Run. Few people know what caused this marathon run.
Miltiades decided to send Phidipides to spread the news of the victory over the Persians in Athens. The latter ran about 42 kilometers without stopping and reached Athens, preaching the walls of the temple of the goddess Artemis. Later, the marathon race was also included in the Olympics.
Now let’s imagine he had a phone. What will happen? Of course, he would call Athens immediately and report what had happened, and he would not have run so long and the marathon run would not have happened.
