We (my dad, 2 brothers, sister and I) were siting and talking in the livingroom in Bogota, Colombia. There was no power in the neiborhood, my dad was sitting forward the window when he saw something that kept his atention, we look in that direction. There were 3 green lights, floating in the sky not to far from us, suddenly they changed positions very fast but they ketp the same line, we went out to see it better we didin't even talk to each other, we were amazed about it. They were there for about 15 min. After they left, we started to talk, we all knew they were ufos... When thry left it seen like they just disappear
