V shaped craft with 5-7 diffused lights. Directly overhead, flying low, traveling from west to east. Silent and fast

We were in the backyard at my cousin’s, celebrating his birthday. I wandered away from the porch to look at the stars. I was looking straight up, facing the southern sky and noticed a very faint, bluish white light. It looked as if someone was pointing a flashlight through fog, but the sky was clear of any clouds. As my eyes focused and adjusted, I saw more of the same lights. They were all in a V formation like the way geese fly. The lights appeared to fall in and out of sync ever so slightly, which made me think it might have been multiple craft. This all took place within a matter of seconds. I was stunned and couldn’t believe what I was seeing. The only thing I could do was mutter an expletive to myself. As it passed over the house, out of my line of sight, I ran to the opposite end of the backyard to see if I could follow it again, but it was gone. I returned to the group and told them what I saw.
