Nuclear weapon tests caused a powerful shift of tectonic plates and a series of earthquakes of the highest magnitude, the oscillations circled the moon several times in a row, forming giant cracks on the surface. A geolocation scan of the landscape revealed abnormal voids beneath the surface of the moon. It was customary to send an expedition of scientists to places of gigantic faults where they discovered entire cities and civilization hidden in the bowels of the planet. Research and analysis revealed that the race inhabiting the moon was our direct relatives and possibly the first-born. But where did they go and what happened? Everything looked abandoned, as if everyone had abandoned in a hurry, running away from something inevitable. While exploring the temples, one of the teams of scientists stumbled upon a grandiose monument, having studied which they were able to randomly activate it. The hologram of the star map sowed and illuminated everything for many kilometers. It was definitely a message, the coordinates of the place where the first-born went in a hurry leaving the moon were encrypted. It was also possible to understand and study some technologies, one of which was hypersonic engines. Now it will not be difficult for humanity to find our ancestors lost in the depths of space and find out what happened to them.
