The word "Mars" written In the Sky by lights

My girlfriend and I went outside to walk our dogs in Palm Springs, Ca, and we saw the craziest lights.  There were hundreds of lights in the sky that were made to spell "MARS".
Each letter seemed to be a quarter mile long and each letter was composed of dozens of individual lights.  Each letter also flashed at the same time and the same exact color.  It was surreal.  The word "Mars" lasted in the sky for over 30 seconds, proving it was not fireworks and there was no way these were drones.  The lights were insanely bright!  The letter "M" was comprised of dozens of red lights, the "A" were dozens of blue lights and so on.  My stomach dropped when I saw these because there was no way this was man made.
As the lights dimmed and shut off, there was a lasting blue hue from each individual light, and it then turned to just a few twinkling lights in the sky until there was Darkness.  No smoke,  Just clear black sky.
