Standing in the backyard of my house looking up stargazing

Me and my brother was burning garbage at night I'm going to say if it's around 8:39 p.m. third week of September he was still warm I looked up all of a sudden something I just had a feeling to look up and Bam they was going south to North and they was coming up to this white box looking thing in the sky they was white they had no bottom to the triangle it looks like something that you would point a directional pointer on the interstate but they was going in this white box and just as fast as I was going in when was coming back out but they was doing a 90° left-hand turn and splitting West soon after that I didn't see him no more but I had a funny feeling in my gut that they know that we was watching them thank you for your time
