Lima-Peru 1978 Two girls(17&13) spot a red hexagon shape w. red light floating ~ 12 ft above their heads.

My aunt(17) and I (13) were riding her moped, we were just about 50 yards from her house, we were taking a short cut through an alley ( wide open alley ), when the engine of the bike suddenly stopped, we were thinking, it has gas.. got off the moped and stared checking for any lose hose when we looked up about 12-14 feet above us there was something floting... something in an exagon shape small a little less than 2 feet high, red with a red beaming light in the bottom... we looked around and notice no wire or nothing this thing was in the air...we thuoght what is that... (there was not a toy or anything we've ever heard that was able to do that), notice the light like going on and off and got really frighten and run pushing the bike.. we did not look back... we've never heard of something like that, we told my aunt other aunt my aunt older sister... we were super scared she though we were making up a story...she said let go...we did not care if she believed us or not but wedid not want to go back to see if it was there and decided we were not going to tell our story anymore. It's been about 29 years since that happend.
