Yes, if we were photons that would be valid argument, but we are not.
Time needed for light to travel from nearest star to Earth is like ~5years. Pretty slow way of exchanging information, considering that most stars are hundreds, thousands, millions (I don't remember the proper number, but you get the idea) lightyears from Earth.
In other words, to photons which are traveling with a speed of light, seemingly no time has passed since their departure from Alpha Centauri, but for us it was 5 years, because we are not traveling with a speed of light.
(I wasn't really good at my quantum physics classes at uni, so if you see a mistake in my reasoning then please let me know. Also check out twin paradox, it's pretty much the same thing).
